[alsa-devel] [PATCH v2] sound: dmasound_atari: Mark expected switch fall-through

[Gustavo A. R. Silva]

Mark switch cases where we are expecting to fall through.

This patch fixes the following warning (Building: m68k):

sound/oss/dmasound/dmasound_atari.c: warning: this statement may fall
through [-Wimplicit-fallthrough=]:  => 1449:24

Notice that, in this particular case, the code comment is
modified in accordance with what GCC is expecting to find.

Changes in v2:
 - Update code so switch and case statements are at the same indent.
