HID: hid-lg: make array cbuf static const to shink object code size
Don't populate array cbuf on the stack, instead make it static. Makes the object code smaller by over 110 bytes: Before: text data bss dec hex filename 15096 3504 128 18728 4928 drivers/hid/hid-lg.o After: text data bss dec hex filename 14884 3600 128 18612 48b4 drivers/hid/hid-lg.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
