From 61c0596c5fbef99df5518ae449be4ab49a2c2233 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 14 Nov 2006 22:35:43 +0900 Subject: [PATCH] [PATCH] libata: trivial updates to ata_sg_init_one() There's no need to memset &qc->sgent manually, sg_init_one() clears sgent inside it. Also, kill not-so-necessary sg local variable.
