[PATCH 1/5] imx-drm: ipu-di: Check the return value from clk_prepare_enable()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>

clk_prepare_enable() may fail, so let's check its return value and propagate it
in the case of error.
