      ASoC: imx-sgtl5000: Fix uninitialized pointer use in error path · 50d4a790
      Philipp Zabel authored
      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]

      ASoC: imx-sgtl5000: do not use devres on a foreign device · a8b22c1c
      Philipp Zabel authored
      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
      the imx-sgtl5000 error path:
      
      imx-sgtl5000 sound.12: snd_soc_register_card failed (-517)
      platform sound.12: Driver imx-sgtl5000 requests probe deferral

      cfq: explicitly use 64bit divide operation for 64bit arguments · f3cff25f
      Anatol Pomozov authored
      'samples' is 64bit operant, but do_div() second parameter is 32.
      do_div silently truncates high 32 bits and calculated result
      is invalid.
      
      In case if low 32bit of 'samples' are zeros then do_div() produces
      kernel crash.
