Subject: ALSA: oss: consolidate kmalloc/memset 0 call to kzalloc
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=46325371b230cc66c743925c930a17e7d0b8211e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: oss: consolidate kmalloc/memset 0 call to kzalloc

This is an API consolidation only. The use of kmalloc + memset to 0
is equivalent to kzalloc.
