Replace the sparse 256-pointer array for looking up protocol strings by a switch() statement to reduce kernel size. According to bloat-o-meter, this saves 910 bytes on m68k (32-bit), and 1892 bytes on arm64 (64-bit). Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>Gees, thanks for catching that. Applied to libata/for-4.11.
Thanks!
There are two more that annoy me, but I don't know how to fix them:
ata_scsi_rbuf - 4096 +4096
ata_force_param_buf - 4096 +4096
