X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e4baf488ab67556fb6d2b4c9748d1d56e25c5cee;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ASoC: mxs-saif: Handle errors for clk_enable

[ Upstream commit 2ecf362d220317debf5da376e0390e9f7a3f7b29 ]

As the potential failure of the clk_enable(),
it should be better to check it, like mxs_saif_trigger().
