Subject: [PATCH] ASoC: ak4458: rstn_control - return a non-zero on error only

[ Upstream commit 176a11834b65ec35e3b7a953f87fb9cc41309497 ]

snd_soc_component_update_bits() may return 1 if operation
was successful and the value of the register changed.
Return a non-zero in ak4458_rstn_control for an error only.
