ata: pata_artop: make arrays static const, makes object smaller
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) Acked-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
