From 764cce442e6135459027aa7fdabbd0bb6e8f3ca9 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Thu, 15 Jun 2017 21:02:20 -0700 Subject: i965/miptree: Rename the non_msrt_mcs functions to _ccs While we're here, we also make the two support checks static since there are no users outside intel_mipmap_tree.c.
