Subject: [PATCH v2] sh: kernel: disassemble: Mark expected switch
fall-throughs
Remove logically dead code and mark switch cases where we are expecting
to fall through.
Fix the following warnings (Building: defconfig sh):
arch/sh/kernel/disassemble.c:478:8: warning: this statement may fall
through [-Wimplicit-fallthrough=]
arch/sh/kernel/disassemble.c:487:8: warning: this statement may fall
through [-Wimplicit-fallthrough=]
arch/sh/kernel/disassemble.c:496:8: warning: this statement may fall
through [-Wimplicit-fallthrough=]
Signed-off-by: Gustavo A. R. Silva <gustavo@...eddedor.com>

Changes in v2:
- Remove logically dead code. Pointed out by Joe Perches.
NOTE: If no one cares, I'll apply this to my tree and queue it up
for 5.3-rc4.
