Subject: scsi: mpt3sas: Mark expected switch fall-through
Patch-mainline: v5.3-rc1
Git-commit: 6ea3b189f7704f0881815b414a20f36a2529030c
References: bsc#1143738
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where
we are expecting to fall through.
This patch fixes the following warning:
drivers/scsi/mpt3sas/mpt3sas_base.c: In function _base_update_ioc_page1_inlinewith_perf_mode :
drivers/scsi/mpt3sas/mpt3sas_base.c:4510:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (ioc->high_iops_queues) {
^
drivers/scsi/mpt3sas/mpt3sas_base.c:4530:2: note: here
case MPT_PERF_MODE_LATENCY:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
