[ Upstream commit 1a37b6738b58d86f6b144b3fc754ace0f2e0166d ]
Since the sata_cmd struct is zeroed out before its fields are initialized, there is no need for using "|=" to initialize the ncqtag_atap_dir_m field. Using a standard assignment removes the sparse warning:
warning: invalid assignment: |=
Also, since the ncqtag_atap_dir_m field has type __le32, use cpu_to_le32() to generate the assigned value.
