Subject: [PATCH] ASoC: amd: add missed checks for clk_get()
Date: Thu, 3 Dec 2020 22:31:16 +0800 [thread overview]
Message-ID: <20201203143116.405930-1-hslester96@gmail.com> (raw)
cz_da7219_init() does not check the return value of clk_get(),
while da7219_clk_enable() calls clk_set_rate() to dereference
the pointers.
Add checks to fix the problems.
Fixes: bb24a31ed584 ("ASoC: AMD: Configure wclk and bclk of master codec")
