Subject[GIT PULL] ACPI and power management fixes for v3.12-rc3
Date
Hi Linus,

Please pull from the git repository at

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm+acpi-3.12-rc3

to receive ACPI and power management fixes for v3.12-rc3 with
top-most commit dcc7bc3f3d91bbd5c15409a92317c2c24449a285

Merge branch 'pm-cpufreq-fixes'

on top of commit 4a10c2ac2f368583138b774ca41fac4207911983

Linux 3.12-rc2

These fix one recent cpufreq regression, a few older bugs that may
harm users and a kerneldoc typo.

Specifics:

1) After recent locking changes in the cpufreq core it is possible
to trigger BUG_ON(!policy) in lock_policy_rwsem_read() if
cpufreq_get() is called before registering a cpufreq driver.
Fix from Viresh Kumar.

2) If intel_pstate has been loaded already, it doesn't make sense
to do anything in acpi_cpufreq_init() and moreover doing something
in there in that case may be harmful, so make that function return
immediately if another cpufreq driver is already present. From
Yinghai Lu.

3) The ACPI IPMI driver sometimes attempts to acquire a mutex from
interrupt context, which can be avoided by replacing that mutex
with a spinlock. From Lv Zheng.

4) A NULL pointer may be dereferenced by the exynos5440 cpufreq
driver if a memory allocation made by it fails. Fix from
Sachin Kamat.

5) Hanjun Guo's commit fixes a typo in the kerneldoc comment
documenting acpi_bus_unregister_driver().

Thanks!
