X-Git-Tag: v6.19-rc1~156^2~39
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a0deef0ed594a1e1a81a2bab13b7eb115cd59de6;p=thirdparty%2Fkernel%2Flinux.git

ALSA: maestro3: using vmalloc_array() to handle the code

Change array_size() to vmalloc_array(), due to vmalloc_array()
being optimized better, using fewer instructions, and handles
overflow more concisely.
