platform/x86: panasonic-laptop: 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 2505 600 4 3109 c25 drivers/platform/x86/panasonic-laptop.o File size After adding 'const': text data bss dec hex filename 2569 536 4 3109 c25 drivers/platform/x86/panasonic-laptop.o Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Darren Hart (VMware) <dvhart@infradead.org>
