4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
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
