[PATCH] ALSA: Use fallthrough pseudo-keyword

From: Gustavo A. R. Silva
Date: Tue Jul 07 2020 - 13:23:26 EST

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

[1] https://www.kernel.org/doc/html/latest/process/deprecated.html?highlight=fallthrough#implicit-switch-case-fall-through
