Subject: [PATCH] scsi: megaraid_sas: remove unused variables
'debugBlk','fusion'
Git-commit: 8cfb8e40d686a756428c627dccfaff28ca70dd8b
Patch-mainline: v5.5-rc1
References: bsc#1156632,jsc#SLE-10720
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/scsi/megaraid/megaraid_sas_fp.c: In function MR_GetSpanBlock:
drivers/scsi/megaraid/megaraid_sas_fp.c:400:16: warning: variable debugBlk set but not used [-Wunused-but-set-variable]
drivers/scsi/megaraid/megaraid_sas_fp.c: In function mr_spanset_get_phy_params:
drivers/scsi/megaraid/megaraid_sas_fp.c:713:25: warning: variable fusion set but not used [-Wunused-but-set-variable]
drivers/scsi/megaraid/megaraid_sas_fp.c: In function MR_GetPhyParams:
drivers/scsi/megaraid/megaraid_sas_fp.c:815:25: warning: variable fusion set but not used [-Wunused-but-set-variable]
'debugBlk' is introduced by commit 9c915a8c99bc ("[SCSI] megaraid_sas:
Add 9565/9285 specific code"), but never used, so remove it
'fusion' is not used since commit c365178f3147 ("scsi: megaraid_sas:
use adapter_type for all gen controllers")
