[PATCH] libata: return AC_ERR_* from issue functions
Return AC_ERR_* mask from issue fuctions instead of 0/-1. This enables things like failing a qc with AC_ERR_HSM when the device doesn't set DRDY when the qc is about to be issued. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
