4fa8dbc18e ASoC: fsl: imx-sgtl5000: Add .remove back
Commit e8f00c1b01 (Merge remote-tracking branch 'asoc/fix/fsl' into asoc-devm)
fixed a conflict, but missed to add the .remove function back,which causes the
following build warning:

sound/soc/fsl/imx-sgtl5000.c:185:12: warning: 'imx_sgtl5000_remove' defined but not used [-Wunused-function]

Fix the warning by adding the .remove function back.

50d4a790e6 ASoC: imx-sgtl5000: Fix uninitialized pointer use in error path
This patch avoids to dereference the uninitialized data pointer if the
error path is entered before devm_kzalloc is called (or if the allocation
fails). It fixes the following warning:

    sound/soc/fsl/imx-sgtl5000.c: In function 'imx_sgtl5000_probe':
    sound/soc/fsl/imx-sgtl5000.c:175:18: warning: 'data' may be used uninitialized in this function [-Wmaybe-uninitialized]

a8b22c1ccc ASoC: imx-sgtl5000: do not use devres on a foreign device
Calling devm_clk_get with any device pointer other than our own confuses
devres. Use clk_get instead. This avoids hitting the following warning in

Pull i2c updates from Wolfram Sang:
 "Highlights:

   - OF and ACPI helpers are now included in the core, and not in
     external files anymore.  This removes dependency problems for
     modules and is cleaner, in general.
   - mv64xxx-driver gains fifo usage to support mv78230
   - imx-driver overhaul to support VF610
   - various cleanups, most notably related to devm_* and CONFIG_PM
     usage
   - driver bugfixes and smaller feature additions"

687b81d083 i2c: move OF helpers into the core
I2C of helpers used to live in of_i2c.c but experience (from SPI) shows
that it is much cleaner to have this in the core. This also removes a
circular dependency between the helpers and the core, and so we can
finally register child nodes in the core instead of doing this manually
in each driver. So, fix the drivers and documentation, too.

9e13f34588 ASoC: sgtl5000: Let the codec acquire its clock
On a mx6qsabrelite board the following error happens on probe:

sgtl5000: probe of 0-000a failed with error -5
imx-sgtl5000 sound.13: ASoC: CODEC (null) not registered
imx-sgtl5000 sound.13: snd_soc_register_card failed (-517)
platform sound.13: Driver imx-sgtl5000 requests probe defer

Prior to reading the codec ID we need to turn the SYS_MCLK clock, so let's
enable the codec clock inside sgtl5000_i2c_probe().

Also remove the codec clock enable/disable functions from the machine driver.

bd41bc9696 ASoC: fsl: remove use of imx-pcm-audio from fsl_ssi
Rather than instantiating imx-pcm-audio to call imx_pcm_dma_init(),
fsl_ssi can just directly call it to save the use of imx-pcm-audio.
With this change, fsl_ssi becomes not only a cpu DAI but also a platform
device, so updates platform device setup in imx-sgtl5000 accordingly.
