5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen Ni <nichen@xxxxxxxxxxx>
[ Upstream commit 1a70579723fde3624a72dfea6e79e55be6e36659 ]
clk_prepare_enable() may fail, so we should better check its return
value and propagate it in the case of error.
Fixes: 62a7fc32a628 ("ASoC: max98088: Add master clock handling")
