Subject: [PATCH] lib/cmdline.c: mark expected switch fall-throughs
Date: Fri, 25 Jan 2019 14:31:40 -0600 [thread overview]
Message-ID: <20190125203140.GA1814@embeddedor> (raw)
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warnings:
lib/cmdline.c:137:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
lib/cmdline.c:140:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
lib/cmdline.c:143:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
lib/cmdline.c:146:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
lib/cmdline.c:149:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough.
