From a9764c2bb5b6d3c9df91f2977a2a640f55de0dc2 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 15 May 2006 21:03:53 +0900 Subject: [PATCH] [PATCH] ahci: kill pp->cmd_tbl_sg With NCQ, there are multiple sg tables, so pp->cmd_tbl_sg doesn't cut it. Directly calculate sg table address from pp->cmd_tbl.
