Subject: ALSA: ctxfi: Remove null check before kfree
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=39cdc62b1b4efa39831d4de22f990043b0304fff;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: ctxfi: Remove null check before kfree

kfree on NULL pointer is a no-op and therefore checking is redundant.
