      ALSA: hda: tas2781: mark const variables as __maybe_unused · a2d6d8ae
      Arnd Bergmann authored
      An earlier patch changed the DECLARE_TLV_DB_SCALE declaration, but
      now there are additional static const variables that cause
      the same build warnings:
      
      In file included from sound/pci/hda/tas2781_hda_i2c.c:23:

      Mark them all as unused as well.

      Fix the unbalanced pm_runtime_enable in wcd937x-sdw · c51cba47
      Mark Brown authored
      Merge series from Mohammad Rafi Shaik <quic_mohs@quicinc.com>:
      
      This patch set change will fix the unbalanced pm_runtime_enable in wcd937x-sdw soundwire slave.
      
      And removed the string compare with widget name in MIC BIAS settings, instead
      of string compare use the MIC BIAS id's as value.
      
      Removed separate handling for vdd-buck regulator supply which is not
      required. The vdd-buck regulator supply enabled using bulk enable.
      
      Added the error handling in wcd937x_probe() and disable the regulators in error case.
