From 072c44bf24b3384e1e9873df5ddefe2be3aaac8e Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 29 Oct 2014 18:47:07 +0300 Subject: drm/radeon: remove some buggy dead code The calculation of "num_shader_engines" has a precedence bug because the right shift happens before the mask, but this variable is never used so we can just delete it.
