scsi: mptfusion: Remove unnecessary parentheses
Clang warns when multiple pairs of parentheses are used for a single conditional statement. drivers/message/fusion/mptbase.c:338:11: warning: equality comparison with extraneous parentheses [-Wparentheses-equality] if ((ioc == NULL)) ~~~~^~~~~~~ drivers/message/fusion/mptbase.c:338:11: note: remove extraneous parentheses around the comparison to silence this warning if ((ioc == NULL)) ~ ^ ~ drivers/message/fusion/mptbase.c:338:11: note: use '=' to turn this equality comparison into an assignment if ((ioc == NULL)) ^~ = drivers/message/fusion/mptbase.c:342:12: warning: equality comparison with extraneous parentheses [-Wparentheses-equality] if ((pdev == NULL)) ~~~~~^~~~~~~ drivers/message/fusion/mptbase.c:342:12: note: remove extraneous parentheses around the comparison to silence this warning if ((pdev == NULL)) ~ ^ ~ drivers/message/fusion/mptbase.c:342:12: 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'.
