Subject: sysfs: remove signedness from sysfs_get_dirent
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=89cf2a20c3f13dbb4c15a0c6d2e390e700992173;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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:

        return kernfs_find_and_get(parent, name);
