[PATCH 5.10 156/390] ASoC: rsnd: Add check for rsnd_mod_power_on

[Greg Kroah-Hartman]

From: Jiasheng Jiang <jiasheng@xxxxxxxxxxx>

[ Upstream commit 376be51caf8871419bbcbb755e1e615d30dc3153 ]

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")
