Merge series "ASoC: Intel: bytcr_rt5651: few cleanups" from Andy Shevchenko <andriy.shevchenko@linux.intel.com>:

The small set of cleanups against bytcr_rt5651 board file.

In v2:
- added commit message to patch 2 (Joe, Pierre)
- added cover letter (Pierre)
- added Hans to Cc list (Hans)

Andy Shevchenko (4):
  ASoC: Intel: bytcr_rt5651: Get platform data via dev_get_platdata()
  ASoC: Intel: bytcr_rt5651: Use temporary variable for struct device
  ASoC: Intel: bytcr_rt5651: use devm_clk_get_optional() for mclk
  ASoC: Intel: bytcr_rt5651: Utilize dev_err_probe() to avoid log
    saturation
