X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=47966e977952856f184c93c4ae5da11e151cb4a3;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ALSA: compress: Use kzalloc() for ioctls writing back data

Like the previous patch by Dan, we should clear the data to be
returned from certain compress ioctls, namely,
snd_compr_get_codec_caps() and snd_compr_get_params().
This time, we can simply replace kmalloc() with kzalloc().
