[PATCH] ASoC: rsnd: Add check for rsnd_mod_power_on

From: Jiasheng Jiang
Date: Thu Sep 01 2022 - 03:13:05 EST


As rsnd_mod_power_on() can return negative numbers,
it should be better to check the return value and
deal with the exception.

Fixes: e7d850dd10f4 ("ASoC: rsnd: use mod base common method on SSI-parent")
