This fixes a regression after a kernel change in 4.14.200 [1] that
led to build failure on oxnas/ox820:
drivers/ata/sata_oxnas.c:2238:13: error: initialization of
'enum ata_completion_errors (*)(struct ata_queued_cmd *)'
from incompatible pointer type
'void (*)(struct ata_queued_cmd *)' [-Werror=incompatible-pointer-types]
.qc_prep = sata_oxnas_qc_prep,
^~~~~~~~~~~~~~~~~~
drivers/ata/sata_oxnas.c:2238:13: note:
(near initialization for 'sata_oxnas_ops.qc_prep')
Our local driver is changed the same way as prototyped in the
kernel patch, i.e. return type is changed and AC_ERR_OK return
value is added.
