Subject: [PATCH] i3c: master: dw-i3c-master: mark expected switch fall-through
Date: Mon, 11 Feb 2019 16:14:13 -0600 [thread overview]
Message-ID: <20190211221413.GA21822@embeddedor> (raw)
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/i3c/master/dw-i3c-master.c: In function ‘dw_i3c_master_bus_init’:
drivers/i3c/master/dw-i3c-master.c:603:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (ret)
^
drivers/i3c/master/dw-i3c-master.c:605:2: note: here
case I3C_BUS_MODE_PURE:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
