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:

'name' here

Alternatively, maybe
KBUILD_CFLAGS += $(call cc-disable-warning, pointer-sign)
should be added elsewhere like
arch/x86/boot/compressed/Makefile
