be built, which handles various National Instruments ISA-PNP data
acquisition cards.  The configuration option currently depends on
ISAPNP.

The "ni_atmio" module is a "legacy" comedi driver with no
auto-configuration support and it doesn't register as a PNP card driver.
The only difference in initialization from the other comedi ISA card
drivers is that it will use the ISA-PNP functions to find, attach and
activate the card if no I/O base address has been specified by the user
in the COMEDI_DEVCONFIG ioctl.

The module compiles fine without the ISAPNP configuration option as the
<linux/isapnp.h> and <linux/pnp.h> headers provide dummy inline
functions if the ISAPNP and PNP options, respectively, are not enabled.

Remove the dependancy on the ISAPNP option since the module builds
without it and can be used without it.

(There is a very slim chance that comedi will support proper ISA PNP
drivers one day, in which case the ni_atmio driver could be converted to

As reported, this driver causes problems when built into the kernel, so
force it to be a module until those issues are fixed.

Also delete the "default n" lines in the Kconfig, as they are not
needed.

Rafael J. Wysocki [Thu, 25 Jul 2013 19:43:39 +0000 (21:43 +0200)]
Revert "ACPI / video / i915: No ACPI backlight if firmware expects Windows 8"

We attempted to address a regression introduced by commit a57f7f9
(ACPICA: Add Windows8/Server2012 string for _OSI method.) after which
ACPI video backlight support doesn't work on a number of systems,
because the relevant AML methods in the ACPI tables in their BIOSes
become useless after the BIOS has been told that the OS is compatible
with Windows 8.  That problem is tracked by the bug entry at:

https://bugzilla.kernel.org/show_bug.cgi?id=51231

Commit 8c5bd7a (ACPI / video / i915: No ACPI backlight if firmware
expects Windows 8) introduced for this purpose essentially prevented
the ACPI backlight support from being used if the BIOS had been told
that the OS was compatible with Windows 8 and the i915 driver was
loaded, in which case the backlight would always be handled by i915.
Unfortunately, however, that turned out to cause problems with
backlight to appear on multiple systems with symptoms indicating that
i915 was unable to control the backlight on those systems as
expected.

For this reason, revert commit 8c5bd7a, but leave the function
acpi_video_backlight_quirks() introduced by it, because another
commit on top of it uses that function.

Steven Rostedt (Red Hat) [Wed, 24 Jul 2013 02:21:59 +0000 (22:21 -0400)]
tracing: Remove locking trace_types_lock from tracing_reset_all_online_cpus()

Commit a82274151af "tracing: Protect ftrace_trace_arrays list in trace_events.c"
added taking the trace_types_lock mutex in trace_events.c as there were
several locations that needed it for protection. Unfortunately, it also
encapsulated a call to tracing_reset_all_online_cpus() which also takes
the trace_types_lock, causing a deadlock.

This happens when a module has tracepoints and has been traced. When the
module is removed, the trace events module notifier will grab the
trace_types_lock, do a bunch of clean ups, and also clears the buffer
by calling tracing_reset_all_online_cpus. This doesn't happen often
which explains why it wasn't caught right away.

Commit a82274151af was marked for stable, which means this must be
sent to stable too.

Olof Johansson [Wed, 24 Jul 2013 15:42:27 +0000 (08:42 -0700)]
mfd: max8925: fix dt code for backlight

The device-tree enablement for max8925 has several problems, but besides
the bindings being wrong (and not having seen review) there's also some
bad coding practices on how to fill in the platform_data from device tree.

I came across this since it causes a warning when compiling
mmp2_defconfig, and instead of doing the minimal fix to silence the
warning, I restructured the code a bit.

This silences the warning:
drivers/video/backlight/max8925_bl.c: In function 'max8925_backlight_probe':
drivers/video/backlight/max8925_bl.c:177:3: warning: statement with no effect [-Wunused-value]

Note that the bindings themselves need to be revisited too, but that will
affect more than just the backlight driver and is best done separately;
this just fixes the bad code for the backlight driver.
