>From c29850388327d9cc6c0370b1fc0d0920df92bffe Mon Sep 17 00:00:00 2001 From: Alex Deucher <[email protected]> Date: Fri, 5 Feb 2010 00:55:32 -0500 Subject: [PATCH] drm/radeon/kms: dynclks fixes
- only r4xx/r5xx/rs6xx/rs740 have clock gating atom table, so disable it on r6xx. it's already disabled on r7xx - check to make sure the clock_gating hook exists before calling it. This avoids a segfault on asics without that function. - remove unused static power management function.
