[ 47/57] drm/radeon/cik: Fix encoding of number of banks in tiling configuration info

From: Greg Kroah-Hartman
Date: Thu Oct 03 2013 - 00:27:26 EST


3.11-stable review patch. If anyone has any objections, please let me know.

------------------

From: Michel DÃnzer <michel.daenzer@xxxxxxx>

commit a537314e0b539e22934d3cffeb0b1f476e56491c upstream.

There are multiple valid values, not just 0 or 1. Required
to properly support 2D tiling in the userspace drivers.
