[PATCH -next] [media] vcodec: mediatek: Fix return value check in mtk_vcodec_init_enc_pm()

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

 



From: Wei Yongjun <yongjun_wei@xxxxxxxxxxxxxxxxx>

In case of error, the function devm_clk_get() returns ERR_PTR()
and not returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().
