Input: elantech - make arrays debounce_packet static, reduces object code size
Don't populate the arrays debounce_packet on the stack, instead make them static. Makes the object code smaller by over 870 bytes: Before: text data bss dec hex filename 30553 9152 0 39705 9b19 drivers/input/mouse/elantech.o After: text data bss dec hex filename 29521 9312 0 38833 97b1 drivers/input/mouse/elantech.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
