From c2e1b3a496332b90d073bc9dddd3324d660fca24 Mon Sep 17 00:00:00 2001 From: Ben Goz Date: Mon, 18 Aug 2014 14:55:59 +0300 Subject: [PATCH] drm/amdkfd: Fix logic of destroy_queue_nocpsch() This patch rewrites destroy_queue_nocpsch() as the current logic that is implemented in the function is completely flawed. This function is used only in non-HWS mode.
