[PATCH] gpio: 104-idi-48e: make array register_offset static, makes object smaller

From: Colin King
Date: Sun Oct 06 2019 - 10:43:11 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the array register_offset on the stack but instead make it
static. Makes the object code smaller by 63 bytes. Also add the int type
specifier to clean up a checkpatch warning.

Before:
text data bss dec hex filename
9212 5712 1408 16332 3fcc drivers/gpio/gpio-104-idi-48.o

After:
text data bss dec hex filename
9085 5776 1408 16269 3f8d drivers/gpio/gpio-104-idi-48.o

(gcc version 9.2.1, amd64)
