drm/panel: use mipi_dsi_dcs_write_buffer where possible

A few of the new panels create a local macro wrapping around
mipi_dsi_dcs_write. At the same time, they don't really care about the

mipi_dsi_dcs_write does a kmalloc/memcpy/kfree for payload > 7 bytes.

drm/mipi-dbi: Remove ->enabled

The atomic helpers try really hard to not lose track of things,
duplicating enabled tracking in the driver is at best confusing.
Double-enabling or disabling is a bug in atomic helpers.

In the fb_dirty function we can just assume that the fb always exists,
simple display pipe helpers guarantee that the crtc is only enabled
together with the output, so we always have a primary plane around.

Now in the update function we need to be a notch more careful, since
that can also get called when the crtc is off. And we don't want to

When validating a mode, bridges may need to do so in the context of a

Output status detection is implemented using the same backend as for the

optional as no pointer to the connector is available to the bridge

refactoring of hot plug handling code.

Hot plug detection is notified through the bridge HPD notification
framework when the bridge is used without creating a connector, and
falls back to the existing implementation otherwise. CEC handling of

samples: watch_queue: build sample program for target architecture

This userspace program includes UAPI headers exported to usr/include/.
'make headers' always works for the target architecture (i.e. the same
architecture as the kernel), so the sample program should be built for
the target as well. Kbuild now supports 'userprogs' for that.

I also guarded the CONFIG option by 'depends on CC_CAN_LINK' because
$(CC) may not provide libc.

Revert "Makefile: install modules.builtin even if CONFIG_MODULES=n"

This reverts commit e0b250b57dcf403529081e5898a9de717f96b76b,
which broke build systems that need to install files to a certain
path, but do not set INSTALL_MOD_PATH when invoking 'make install'.

  $ make INSTALL_PATH=/tmp/destdir install
  mkdir: cannot create directory ‘/lib/modules/5.8.0-rc1+/’: Permission denied
  Makefile:1342: recipe for target '_builtin_inst_' failed
  make: *** [_builtin_inst_] Error 1

While modules.builtin is useful also for CONFIG_MODULES=n, this change
in the behavior is quite unexpected. Maybe "make modules_install"
can install modules.builtin irrespective of CONFIG_MODULES as Jonas
originally suggested.

Anyway, that commit should be reverted ASAP.

Pull libnvdimm updates from Dan Williams:
 "A feature (papr_scm health retrieval) and a fix (sysfs attribute
  visibility) for v5.8.

  Vaibhav explains in the merge commit below why missing v5.8 would be
  painful and I agreed to try a -rc2 pull because only cosmetics kept
  this out of -rc1 and his initial versions were posted in more than
  enough time for v5.8 consideration:

    customers in upcoming distros releases (RHEL and SLES) whose

    Being able to track the health of an nvdimm is critical for our
    customers that are running workloads leveraging papr-scm nvdimms.
    Missing the 5.8 kernel would mean missing the distro timelines and
    shifting forward the availability of this feature in distro kernels
    by at least 6 months'

  Summary:

   - Fix the visibility of the region 'align' attribute.

     The new unit tests for region alignment handling caught a corner
     case where the alignment cannot be specified if the region is
     converted from static to dynamic provisioning at runtime.

   - Add support for device health retrieval for the persistent memory
     supported by the papr_scm driver.

     This includes both the standard sysfs "health flags" that the nfit

afs: Fix hang on rmmod due to outstanding timer

The fileserver probe timer, net->fs_probe_timer, isn't cancelled when
the kafs module is being removed and so the count it holds on
net->servers_outstanding doesn't get dropped..

This causes rmmod to wait forever.  The hung process shows a stack like:

afs_purge_servers+0x1b5/0x23c [kafs]
afs_net_exit+0x44/0x6e [kafs]
ops_exit_list+0x72/0x93
unregister_pernet_operations+0x14c/0x1ba
unregister_pernet_subsys+0x1d/0x2a
afs_exit+0x29/0x6f [kafs]
__do_sys_delete_module.isra.0+0x1a2/0x24b
do_syscall_64+0x51/0x95
entry_SYSCALL_64_after_hwframe+0x44/0xa9

Fix this by:

 (1) Attempting to cancel the probe timer and, if successful, drop the
     count that the timer was holding.

 (2) Make the timer function just drop the count and not schedule the
     prober if the afs portion of net namespace is being destroyed.

Also, whilst we're at it, make the following changes:

 (3) Initialise net->servers_outstanding to 1 and decrement it before
     waiting on it so that it doesn't generate wake up events by being
     decremented to 0 until we're cleaning up.

 (4) Switch the atomic_dec() on ->servers_outstanding for ->fs_timer in
     afs_purge_servers() to use the helper function for that.

afs: Fix afs_do_lookup() to call correct fetch-status op variant

Fix afs_do_lookup()'s fallback case for when FS.InlineBulkStatus isn't
supported by the server.

In the fallback, it calls FS.FetchStatus for the specific vnode it's
meant to be looking up.  Commit b6489a49f7b7 broke this by renaming one
of the two identically-named afs_fetch_status_operation descriptors to
something else so that one of them could be made non-static.  The site
that used the renamed one, however, wasn't renamed and didn't produce
any warning because the other was declared in a header.

Fix this by making afs_do_lookup() use the renamed variant.

Note that there are two variants of the success method because one is

drm/bridge: tfp410: fix de-skew value retrieval from DT

The tfp410 has a data de-skew feature that allows the user to compensate
the skew between IDCK and the pixel data and control signals.

In the driver, the setup and hold times are calculated from the de-skew
value. This retrieves the deskew value from the DT using the proper
datatype and range check as described by the binding (u32 from 0 to 7).

This fix results from a change in the ti,tfp410 DT binding.

This changes how the 'ti,deskew' property is defined. It's now an

Until the dtc carries the integer sign through to the yaml output it's

drm/panel-simple: Add missing connector type for some panels

The DRM panel bridge core requires connector type to be set up properly,
otherwise it rejects the panel. The missing connector type problem popped
up while I was trying to wrap CLAA070WP03XG panel into a DRM bridge in
order to test whether panel's rotation property work properly using
panel-simple driver on NVIDIA Tegra30 Nexus 7 tablet device, which uses
CLAA070WP03XG display panel.

The NVIDIA Tegra DRM driver recently gained DRM bridges support for the
RGB output and now driver wraps directly-connected panels into DRM bridge.
Hence all panels should have connector type set properly now, otherwise
the panel's wrapping fails.

This patch adds missing connector types for the LVDS panels that are found
on NVIDIA Tegra devices:

  1. AUO B101AW03
  2. Chunghwa CLAA070WP03XG
  3. Chunghwa CLAA101WA01A

Merge branch 'for-5.8/papr_scm' into libnvdimm-for-next

Include the papr_scm health retrieval feature for v5.8-rc2. The
functionality was initially posted well in advance of the merge window,
but review comments and a late build-bot warning kept them out of the
v5.8-rc1 libnvdimm pull request.

Vaibhav notes:
These patches are tied to specific features that were committed to
customers in upcoming distros releases (RHEL and SLES) whose time-lines
are tied to 5.8 kernel release.

Being able to track the health of an nvdimm is critical for our
customers that are running workloads leveraging papr-scm nvdimms.
Missing the 5.8 kernel would mean missing the distro timelines and
shifting forward the availability of this feature in distro kernels by
at least 6 months.

Merge tag 'overflow-v5.8-rc2' of git://git./linux/kernel/git/kees/linux

Pull flex-array size helper from Kees Cook:
 "During the treewide clean-ups of zero-length "flexible arrays", the
  struct_size() helper was heavily used, but it was noticed that many
  times it would have been nice to have an additional helper to get the
  size of just the flexible array itself.

  This need appears to be even more common when cleaning up the 1-byte
  array "flexible arrays", so Gustavo implemented it.

  I'd love to get this landed early so it can be used during the v5.9
  dev cycle to ease the 1-byte array cleanups."

drm/arm: fix unintentional integer overflow on left shift

Shifting the integer value 1 is evaluated using 32-bit arithmetic
and then used in an expression that expects a long value leads to
a potential integer overflow. Fix this by using the BIT macro to
perform the shift to avoid the overflow.
