From f5e0b5ecb3afc8050259003067b6a1aef3635f12 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Mon, 13 Oct 2008 21:39:45 +0200 Subject: [PATCH] pmac: remove needless pmac_ide_destroy_dmatable() wrapper hwif->sg_nents is always != 0 when this function is called and there is also no need to explicitely zero hwif->sg_nents.
