From b51d577a51296fc6967fbab5d857986617c4f276 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Thu, 20 Sep 2018 13:10:02 -0700 Subject: scsi: mpt3sas: Remove unnecessary parentheses and simplify null checks Clang warns when multiple pairs of parentheses are used for a single conditional statement. drivers/scsi/mpt3sas/mpt3sas_base.c:535:11: warning: equality comparison with extraneous parentheses [-Wparentheses-equality] if ((ioc == NULL)) ~~~~^~~~~~~ drivers/scsi/mpt3sas/mpt3sas_base.c:535:11: note: remove extraneous parentheses around the comparison to silence this warning if ((ioc == NULL)) ~ ^ ~ drivers/scsi/mpt3sas/mpt3sas_base.c:535:11: note: use '=' to turn this equality comparison into an assignment if ((ioc == NULL)) ^~ = drivers/scsi/mpt3sas/mpt3sas_base.c:539:12: warning: equality comparison with extraneous parentheses [-Wparentheses-equality] if ((pdev == NULL)) ~~~~~^~~~~~~ drivers/scsi/mpt3sas/mpt3sas_base.c:539:12: note: remove extraneous parentheses around the comparison to silence this warning if ((pdev == NULL)) ~ ^ ~ drivers/scsi/mpt3sas/mpt3sas_base.c:539:12: note: use '=' to turn this equality comparison into an assignment if ((pdev == NULL)) ^~ = 2 warnings generated. Remove them and while we're at it, simplify the NULL checks as '!var' is used more than 'var == NULL'. Signed-off-by: Nathan Chancellor Signed-off-by: Martin K.
