Mutexes should not be acquired in interrupt context. While the trylock
fastpath is arguably safe on all implementations, the slowpath
unlock path definitely isn't. This fixes the following lockdep splat:

Having nouveau builtin would still allow ACPI_VIDEO to be used as external module
if some of the deps for acpi_video have not been met, which would result in a linking

git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/late
From David Brown:
MSM clock updates for 3.11.
Per Stephen Boyd's coverletter:
Resending to collect higher level maintainer acks per Olof's request.
The plan is to push this patchset through MSM to the arm-soc tree.
This patchset moves the existing MSM clock code and affected drivers
to the common clock framework. A prerequisite of moving to the common
clock framework is to use clk_prepare() and clk_enable() so the first
few patches migrate drivers to that call (clk_prepare() is a no-op on
MSM right now). It also removes some custom clock APIs that MSM
provides and finally moves the proc_comm clock code to the common
struct clk.
This patch series will be used as the foundation of the MSM 8660/8960
clock code that I plan to send out after this series.

git://people.freedesktop.org/~danvet/drm-intel into drm-next
Last 3.11 feature pull. I have a few odds bits and pieces and fixes in my
queue, I'll sort them out later on to see what's for 3.11-fixes and what's
for 3.12. But nothing to hold this here up imo.
Highlights:
- more hangcheck work from Mika and Chris to prepare for arb robustness
- trickle feed fixes from Ville
- first parts of the shared pch pll rework, with some basic hw state
readout and cross-checking (this shuts up the confused pch pll refcount
WARN that Linus just recently forwarded)
- Haswell audio power well support from Wang Xingchao (alsa bits acked by
Takashi)
- some cleanups and asserts sprinkling around the plane/gamma enabling
sequence from Ville
- more gtt refactoring from Ben
- clear up the adjusted->mode vs. pixel clock vs. port clock confusion
- 30bpp support, this time for real hopefully

The SRP initiator implements host reset by reconnecting to the SRP
target. That means that communication with the target is possible as
soon as host reset finished. Hence skip the host settle delay.

The SCSI error handler assumes that the transport layer is operational
if an eh_abort_handler() returns SUCCESS. Hence srp_abort() only
should return SUCCESS if sending the ABORT TASK task management
function succeeded. This patch avoids the SCSI error handler skipping
the srp_reset_host() call after a transport layer error.
