| |
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/net/ethernet/chelsio/cxgb4vf/cxgb4vf_main.c: In function ‘fwevtq_handler’: drivers/net/ethernet/chelsio/cxgb4vf/cxgb4vf_main.c:520:7: warning: this statement may fall through [-Wimplicit-fallthrough=] cpl = (void *)p; ~~~~^~~~~~~~~~~ drivers/net/ethernet/chelsio/cxgb4vf/cxgb4vf_main.c:524:2: note: here case CPL_SGE_EGR_UPDATE: { ^~~~
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.
