From: Colin Ian King <colin.king@canonical.com>

commit 795ef788145ed2fa023efdf11e8d5d7bedc21462 upstream.

Don't populate the arrays cdb on the stack, instead make them static.
Makes the object code smaller by 230 bytes:

Before:
text data bss dec hex filename
3797 240 0 4037 fc5 drivers/ata/libata-zpodd.o

After:
text data bss dec hex filename
3407 400 0 3807 edf drivers/ata/libata-zpodd.o
