Subject: ALSA: ac97c: Fix an error handling path in 'atmel_ac97c_probe()'
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0515760fa1159ffa863c7b2b73466aaff7d11a80;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: ac97c: Fix an error handling path in 'atmel_ac97c_probe()'

If 'clk_prepare_enable()' fails, we must release some resources before
returning. Add a new label in the existing error handling path and 'goto'
there.
