From 89cf2a20c3f13dbb4c15a0c6d2e390e700992173 Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Sun, 21 May 2017 01:58:07 -0700 Subject: [PATCH] sysfs: remove signedness from sysfs_get_dirent sysfs_get_dirent is usually invoked with a string literal, which have the type char[]. While the toplevel Makefile disables -Wpointer-sign, other Makefiles like arch/x86/boot/compressed/Makefile redefine KBUILD_CFLAGS. Fixes the warning: In file included from arch/x86/boot/compressed/kaslr.c:17: In file included from ./include/linux/module.h:17: In file included from ./include/linux/kobject.h:21: ./include/linux/sysfs.h:517:37: warning: passing 'const unsigned char *' to parameter of type 'const char *' converts between pointers to integer types with different sign [-Wpointer-sign] return kernfs_find_and_get(parent, name); ^~~~ ./include/linux/kernfs.h:462:57: note: passing argument to parameter 'name' here kernfs_find_and_get(struct kernfs_node *kn, const char *name) ^ Signed-off-by: Nick Desaulniers Signed-off-by: Greg Kroah-Hartman --- include/linux/sysfs.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/linux/sysfs.h b/include/linux/sysfs.h index c6f0f0d0e17e..aa02c328dff5 100644 --- a/include/linux/sysfs.h +++ b/include/linux/sysfs.h @@ -512,7 +512,7 @@ static inline void sysfs_notify_dirent(struct kernfs_node *kn) } static inline struct kernfs_node *sysfs_get_dirent(struct kernfs_node *parent, - const unsigned char *name) + const char *name) { return kernfs_find_and_get(parent, name); }
