scsi: mptfusion: Remove unnecessary parentheses

2018-09-28T06:13:33Z

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'.

scsi: message: fusion: Replace GFP_ATOMIC with GFP_KERNEL

2018-07-31T03:17:53Z

mpt_attach() and mptfc_probe() are never called in atomic context. They call kzalloc() and kcalloc() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself. Signed-off-by: Jia-Ju Bai Signed-off-by: Martin K. Petersen

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2018-06-10T20:01:12Z

Pull SCSI updates from James Bottomley: "This is mostly updates to the usual drivers: ufs, qedf, mpt3sas, lpfc, xfcp, hisi_sas, cxlflash, qla2xxx. In the absence of Nic, we're also taking target updates which are mostly minor except for the tcmu refactor. The only real core change to worry about is the removal of high page bouncing (in sas, storvsc and iscsi).

treewide: Fix function prototypes for module_param_call()

2017-10-31T14:30:37Z

Several function prototypes for the set/get functions defined by module_param_call() have a slightly wrong argument types. This fixes those in an effort to clean up the calls when running under type-enforced compiler instrumentation for CFI. This is the result of running the following semantic patch: @match_module_param_call_function@ declarer name module_param_call; identifier _name, _set_func, _get_func; expression _arg, _mode; @@ module_param_call(_name, _set_func, _get_func, _arg, _mode); @fix_set_prototype depends on match_module_param_call_function@ identifier match_module_param_call_function._set_func; identifier _val, _param; type _val_type, _param_type; @@ int _set_func( -_val_type _val +const char * _val , -_param_type _param +const struct kernel_param * _param ) { ... } @fix_get_prototype depends on match_module_param_call_function@ identifier match_module_param_call_function._get_func; identifier _val, _param; type _val_type, _param_type; @@ int _get_func( -_val_type _val +char * _val , -_param_type _param +const struct kernel_param * _param ) { ... } Two additional by-hand changes are included for places where the above Coccinelle script didn't notice them: drivers/platform/x86/thinkpad_acpi.c fs/lockd/svc.c Signed-off-by: Kees Cook Signed-off-by: Jessica Yu
