HID: asus: make array 'buf' static const
Don't populate the const read-only array 'buf' on the stack but instead make it static. Makes the object code smaller by 26 bytes: Before: text data bss dec hex filename 14378 2384 64 16826 41ba linux/drivers/hid/hid-asus.o After: text data bss dec hex filename 14296 2440 64 16800 41a0 linux/drivers/hid/hid-asus.o (gcc version 7.2.0 x86_64) [jkosina@suse.cz: change commit message slightly] Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
