| |
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.
