HID: elan: Make array buf static, shrinks object size
Don't populate the array buf on the stack but instead make it static. Makes the object code smaller by 43 bytes: Before: text data bss dec hex filename 7769 1520 0 9289 2449 drivers/hid/hid-elan.o After: text data bss dec hex filename 7662 1584 0 9246 241e drivers/hid/hid-elan.o (gcc version 8.2.0 x86_64) Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
