In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR().

Current code keeps the clocks enabled all the time, it wastes the power
when there is no operaiton on the spi controller.

In order to save the power, this patch adds the two hooks:
   spi_imx_prepare_message: enable the clocks for this message
   spi_imx_unprepare_message: disable the clocks.

This patch also disables the clocks in the end of the probe.

Pull btrfs fix from Chris Mason:
 "Sage hit a deadlock with ceph on btrfs, and Josef tracked it down to a

Pull ACPI and power management fixes from Rafael Wysocki:

 - intel_pstate fix for misbehavior after system resume if sysfs
   attributes are set in a specific way before the corresponding suspend
   from Dirk Brandewie.

 - A recent intel_pstate fix has no effect if unsigned long is 32-bit,
   so fix it up to cover that case as well.

 - The s3c64xx cpufreq driver was not updated when the index field of
   struct cpufreq_frequency_table was replaced with driver_data, so
   update it now.  From Charles Keepax.

 - The Kconfig help text for ACPI_BUTTON still refers to
   /proc/acpi/event that has been dropped recently, so modify it to
   remove that reference.  From Krzysztof Mazur.

 - A Lan Tianyu's change adds a missing mutex unlock to an error code
   path in acpi_resume_power_resources().

 - Some code related to ACPI power resources, whose very purpose is
   questionable to put it lightly, turns out to cause problems to happen
   during testing on real systems, so remove it completely (we may
   revisit that in the future if there's a compelling enough reason).
   From Rafael J Wysocki and Aaron Lu.

Third set of IIO fixes for the 3.12 cycle.

Two little ones this time:

1) A missing clk_unprepare in adf4350.
2) A missing free of the active_scan_mask when iio_disable_all_buffers is
called during an unexpected device removal.  This leak was introduced by
the fix
a87c82e4 iio: Stop sampling when the device is removed
and hence is a regression fix.
