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.
Reported-by: Geert Uytterhoeven geert@linux-m68k.org Signed-off-by: Gustavo A. R. Silva gustavo@embeddedor.com --- Changes in v2: - Update code so switch and case statements are at the same indent.
