rapidio/mport_cdev: mark expected switch fall-through
In preparation for 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.
