Subject[PATCH] input: sidewinder: make array seq static const, makes object smaller
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the array seq on the stack but instead make it
static const. Makes the object code smaller by 30 bytes.

Before:
text data bss dec hex filename
22284 3184 0 25468 637c drivers/input/joystick/sidewinder.o

After:
text data bss dec hex filename
22158 3280 0 25438 635e drivers/input/joystick/sidewinder.o

(gcc version 9.2.1, amd64)
