Subject: [PATCH 0/3] ALSA: use vmalloc_array() to simplify code

Remove array_size() calls and replace vmalloc() with vmalloc_array() to
simplify the code and maintain consistency with existing kmalloc_array()
usage.

vmalloc_array() is also optimized better, resulting in less instructions
being used [1].
