Subject: [PATCH 1/9] ASoC: cs35l41: Handle mdsync_down reg write errors

The return code of regmap_multi_reg_write() call related to "MDSYNC
down" sequence is shadowed by the subsequent
wait_for_completion_timeout() invocation, which is expected to time
timeout in case the write operation failed.

Let cs35l41_global_enable() return the correct error code instead of
-ETIMEDOUT.

Fixes: f5030564938b ("ALSA: cs35l41: Add shared boost feature")
