From 95364f36701e62dd50eee91e1303187fd1a9f567 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 31 Oct 2019 10:59:45 +0100 Subject: ata: make qc_prep return ata_completion_errors In case a driver wants to return an error from qc_prep, return enum ata_completion_errors. sata_mv is one of those drivers -- see the next patch. Other drivers return the newly defined AC_ERR_OK. [v2] use enum ata_completion_errors and AC_ERR_OK.
