[PATCH] i3c: master: dw-i3c-master: mark expected switch fall-through

From: Gustavo A. R. Silva
Date: Mon Feb 11 2019 - 17:14:17 EST

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 âdw_i3c_master_bus_initâ:
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

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enable
