      ASoC: Make soc_component_read() returning an error code again · efc913c8
      Takashi Iwai authored
      Along with the recent unification of snd_soc_component_read*()
      functions, the behavior of snd_soc_component_read() was changed
      slightly; namely it returns the register read value directly, and even
      if an error happens, it returns zero (but it prints an error
      message).  That said, the caller side can't know whether it's an error
      or not any longer.
      
      Ideally this shouldn't matter much, but in practice this seems causing
      a regression, as John reported.  And, grepping the tree revealed that
      there are still plenty of callers that do check the error code, so
      we'll need to deal with them in anyway.
      
      As a quick band-aid over the regression, this patch changes the return
      value of snd_soc_component_read() again to the negative error code.
      It can't work, obviously, for 32bit register values, but it should be
      enough for the known regressions, so far.
      
      Fixes: cf6e26c7 ("ASoC: soc-component: merge snd_soc_component_read() and snd_soc_component_read32()")
