[PATCH][V2] ata: pata_artop: make arrays static const, makes object smaller

From: Colin King
Date: Sun Oct 06 2019 - 10:30:03 EST


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

Don't populate the const arrays on the stack but instead make them
static. Makes the object code smaller by 292 bytes.

Before:
text data bss dec hex filename
6988 3132 128 10248 2808 drivers/ata/pata_artop.o

After:
text data bss dec hex filename
6536 3292 128 9956 26e4 drivers/ata/pata_artop.o

(gcc version 9.2.1, amd64)
