Subject: [PATCH] rapidio/mport_cdev: mark expected switch fall-through
Date: Tue, 12 Feb 2019 11:50:14 -0600
Message-ID: <20190212175014.GA14326@embeddedor> (raw)

n preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/rapidio/devices/rio_mport_cdev.c: In function ‘mport_release_mapping’:
drivers/rapidio/devices/rio_mport_cdev.c:2151:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
   rio_unmap_inb_region(mport, map->phys_addr);
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  CC      drivers/regulator/fixed-helper.o
  CC      drivers/pinctrl/stm32/pinctrl-stm32f429.o
drivers/rapidio/devices/rio_mport_cdev.c:2152:2: note: here
  case MAP_DMA:
  ^~~~

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

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
