Subject: [PATCH] ARM: ep93xx: Mark expected switch fall-through
Date: Wed, 7 Aug 2019 21:38:11 -0500 [thread overview]
Message-ID: <20190808023811.GA14001@embeddedor> (raw)
Mark switch cases where we are expecting to fall through.
Fix the following warnings (Building: arm-ep93xx_defconfig arm):
arch/arm/mach-ep93xx/crunch.c: In function 'crunch_do':
arch/arm/mach-ep93xx/crunch.c:46:3: warning: this statement may
fall through [-Wimplicit-fallthrough=]
memset(crunch_state, 0, sizeof(*crunch_state));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
arch/arm/mach-ep93xx/crunch.c:53:2: note: here
case THREAD_NOTIFY_EXIT:
^~~~
Notice that, in this particular case, the code comment is
modified in accordance with what GCC is expecting to find.
