X-Git-Tag: v4.14-rc1~5480^2~19^2~43^2~39^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=38ebb7034970efe5c7419267e499295e5893b565;p=platform%2Fkernel%2Flinux-rpi.git

ALSA: Consolidate snd_find_free_minor()

A really small cleanup to consolidate snd_find_free_minor() and
snd_kernel_minor() so that we can get rid of one more ifdef.
