Silva Date: Wed, 24 Apr 2019 16:37:32 +0000 (-0500) Subject: cnic: Refactor code and mark expected switch fall-through X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=950347f5f7e407c9ba46c99f44f133de7539b450;p=openwrt%2Fstaging%2Fblogic.git cnic: Refactor code and mark expected switch fall-through In preparation to enabling -Wimplicit-fallthrough, refactor code a bit and mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/net/ethernet/broadcom/cnic.c: In function ‘cnic_cm_process_kcqe’: drivers/net/ethernet/broadcom/cnic.c:4044:11: warning: this statement may fall through [-Wimplicit-fallthrough=] opcode = L4_KCQE_OPCODE_VALUE_CLOSE_COMP; drivers/net/ethernet/broadcom/cnic.c:4050:2: note: here case L4_KCQE_OPCODE_VALUE_RESET_RECEIVED: ^~~~ 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 Signed-off-by: David S.
