isdn_common: Mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/isdn/i4l/isdn_common.c: In function ‘isdn_wildmat’: drivers/isdn/i4l/isdn_common.c:173:5: warning: this statement may fall through [-Wimplicit-fallthrough=] p++; ~^~ drivers/isdn/i4l/isdn_common.c:174:3: note: here default: ^~~~~~~ CC [M] drivers/leds/leds-lp8788.o CC [M] drivers/gpu/drm/amd/amdgpu/../powerplay/smumgr/smu10_smumgr.o drivers/isdn/i4l/isdn_common.c: In function ‘isdn_status_callback’: drivers/isdn/i4l/isdn_common.c:729:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (divert_if) ^ drivers/isdn/i4l/isdn_common.c:732:2: note: here default: ^~~~~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com> Signed-off-by: David S. Miller <davem@davemloft.net>
