Subject: [PATCH V2 0/2] ASoC: ak4458: fail on probe if codec is not present

AK4458 is probed successfully even if AK4458 is not present - this
is caused by probe function returning no error on i2c access failure.
The patchset fixes this.

Changes since V1:
  Conditional statement rewritten as suggested by Mark.

Viorel Suman (2):
  ASoC: ak4458: rstn_control - return a non-zero on error only
  ASoC: ak4458: add return value for ak4458_probe
