platform/x86: alienware-wmi: constify attribute_group structures.
attribute_groups are not supposed to change at runtime. All functions working with attribute_groups provided by <linux/sysfs.h> work with const attribute_group. So mark the non-const structs as const. File size before: text data bss dec hex filename 6932 1016 48 7996 1f3c drivers/platform/x86/alienware-wmi.o File size After adding 'const': text data bss dec hex filename 7060 888 48 7996 1f64 drivers/platform/x86/alienware-wmi.o Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Darren Hart (VMware) <dvhart@infradead.org>
