iio: core: Copy iio_info.attrs->is_visible into iio_dev_opaque.chan_attr_group.is_visible
The iio-core extends the attr_group provided by the driver with its
own attributes. To be able to do this it:
1. Has its own (non const) io_dev_opaque.chan_attr_group attr_group struct
2. It allocates a new attrs array with room for both the drivers and its
own attributes
3. It copies over the driver provided attributes into the newly allocated
attrs array.
But the drivers attr_group may contain more then just the attrs array, it
may also contain an is_visible callback and at least the adi-axi-adc.c
is currently defining such a callback.
Change the attr_group copying code to also copy over the is_visible
callback, so that drivers can define one and have it workins as is
normal for attr_group-s all over the kernel.
Note that the is_visible callback takes an index into the array as
argument, so that indices of the driver's attributes must not change,
this is not a problem as the driver's own attributes are added first
to the newly allocated attrs array and the attributes handled by the
core are appended after the driver's attributes.

iio: xilinx-xadc: Add basic support for Ultrascale System Monitor
The xilinx-xadc IIO driver currently has support for the XADC in the Xilinx
7 series FPGAs. The system-monitor is the equivalent to the XADC in the
Xilinx UltraScale and UltraScale+ FPGAs.
The IP designers did a good job at maintaining backwards compatibility and
only minor changes are required to add basic support for the system-monitor
core.
The non backwards compatible changes are:
* Register map offset was moved from 0x200 to 0x400
* Only one ADC compared to two in the XADC
* 10 bit ADC instead of 12 bit ADC
* Two of the channels monitor different supplies
Add the necessary logic to accommodate these changes to support the
system-monitor in the XADC driver.
Note that this patch does not include support for some new features found
in the system-monitor like additional alarms, user supply monitoring and
secondary system-monitor access. This might be added at a later time.

the output directly written or not. In any case, the uninitialized data
is never used after get_user() fails.
As Dan mentions, it could still trigger an UBSAN runtime error, and it
is of course a bad idea to copy uninitialized variables, so just

proc mountinfo: make splice available again
Since commit
36e2c7421f02 ("fs: don't allow splice read/write without
explicit ops") we've required that file operation structures explicitly
enable splice support, rather than falling back to the default handlers.
Most /proc files use the indirect 'struct proc_ops' to describe their
file operations, and were fixed up to support splice earlier in commits
40be821d627c..
b24c30c67863, but the mountinfo files interact with the
VFS directly using their own 'struct file_operations' and got missed as
a result.
This adds the necessary support for splice to work for /proc/*/mountinfo
and friends.

The problem seems to be dw_pcie_setup_rc() is now called twice before and
after the link up handling. The fix is to move Tegra's link up handling to
.start_link() function like other DWC drivers. Tegra is a bit more
complicated than others as it re-inits the whole DWC controller to retry
the link. With this, the initialization ordering is restored to match the
prior sequence.

Commit
64a1b95bb9fe ("genirq: Restrict export of irq_to_desc()") removed
the export of irq_to_desc() unless powerpc KVM is being built, because
there is still a use of irq_to_desc() in modular code there.
However it used:
#ifdef CONFIG_KVM_BOOK3S_64_HV
Which doesn't work when that symbol is =m, leading to a build failure:
ERROR: modpost: "irq_to_desc" [arch/powerpc/kvm/kvm-hv.ko] undefined!
Fix it by checking for the definedness of the correct symbol which is

scripts: coccicheck: Correct usage of make coccicheck
The command "make coccicheck C=1 CHECK=scripts/coccicheck" results in the
error:
./scripts/coccicheck: line 65: -1: shift count out of range
This happens because every time the C variable is specified,
the shell arguments need to be "shifted" in order to take only
the last argument, which is the C file to test. These shell arguments
mostly comprise flags that have been set in the Makefile. However,
when coccicheck is specified in the make command as a rule, the
number of shell arguments is zero, thus passing the invalid value -1
to the shift command, resulting in an error.
Modify coccicheck to print correct usage of make coccicheck so as to
avoid the error.
