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
