Subject: ALSA: rme32.c irq enabling after spin_lock_irq
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f49a59c4471d81a233e09dda45187cc44fda009d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: rme32.c irq enabling after spin_lock_irq

According to the other code in this driver and similar
code in rme96 it seems, that spin_lock_irq in
snd_rme32_capture_close function should be paired
with spin_unlock_irq.
