Fix this warning:
drivers/rtc/rtc-s5m.c: In function `s5m_rtc_probe':
drivers/rtc/rtc-s5m.c:545: warning: assignment from incompatible pointer type
struct s5m_rtc_info.rtc has type "struct regmap *", while
struct sec_pmic_dev.rtc has type "struct i2c_client *".
Probably the author wanted to assign "struct sec_pmic_dev.regmap", which
has the correct type.
Also, as "rtc" doesn't make much sense as a name for a regmap, rename it
to "regmap".

The W83L786NG stores the fan speed on 4 bits while the sysfs interface
uses a 0-255 range. Thus the driver should scale the user input down
to map it to the device range, and scale up the value read from the
device before presenting it to the user. The reserved register nibble
should be left unchanged.

Some I2C bus drivers do not allow zero-length data transfers which are
required to start a measurement with the HIH6130/1 sensor. Nevertheless,
we can overcome this limitation by writing a zero dummy byte. This byte
is ignored by the sensor and was verified to be working with the OMAP
I2C bus driver in a BeagleBone board.

Commit dc77523c5da5513df1bbc74db2a522a94f4cec0e ensured that m.offset is
only set for the MMAP memory mode by calling __setup_offsets only for that
mode.
However, __setup_offsets also initializes the length fields, and that should
be done regardless of the memory mode. Because of that change the v4l2-ctl
test application fails for the USERPTR mode.
This fix creates a __setup_lengths function that sets the length, and
__setup_offsets just sets the offset and no longer touches the length.

When handling mapping requests, we dereference the SMMU domain before
checking that it is NULL. This patch fixes the issue by removing the check
altogether, since we don't actually use the leaf_smmu when creating
mappings.

When creating IO mappings, we lazily allocate our page tables using the
standard, non-atomic allocator functions. This presents us with a
problem, since our page tables are protected with a spinlock.
This patch reworks the smmu_domain lock to use a mutex instead of a
spinlock. iova_to_phys is then reworked so that it only reads the page
tables, and can run in a lockless fashion, leaving the mutex to guard
against concurrent mapping threads.

Pull SCSI fixes from James Bottomley:
"This is a set of nine fixes (and one author update).
The libsas one should fix discovery in eSATA devices, the WRITE_SAME
one is the largest, but it should fix a lot of problems we've been
getting with the emulated RAID devices (they've been effectively lying
about support and then firmware has been choking on the commands).
The rest are various crash, hang or warn driver fixes"

Pull power management fixes from Rafael Wysocki:
- cpufreq regression fix from Bjørn Mork restoring the pre-3.12
behavior of the framework during system suspend/hibernation to avoid
garbage sysfs files from being left behind in case of a suspend error
- PNP regression fix to restore the correct states of devices after
resume from hibernation broken in 3.12. From Dmitry Torokhov.
- cpuidle fix to prevent cpuidle device unregistration from crashing
due to a NULL pointer dereference if cpuidle has been disabled from
the kernel command line. From Konrad Rzeszutek Wilk.
- intel_idle fix for the C6 state definition on Intel Avoton/Rangeley
processors from Arne Bockholdt.
- Power capping framework fix to make the energy_uj sysfs attribute
work in accordance with the documentation. From Srinivas Pandruvada.
- epoll fix to make it ignore the EPOLLWAKEUP flag if the kernel has
been compiled with CONFIG_PM_SLEEP unset (in which case that flag
should not have any effect). From Amit Pundir.
- cpufreq fix to prevent governor sysfs files from being lost over
system suspend/resume in some (arguably unusual) situations. From
Viresh Kumar.
