Subject: [ 14/26] drm/radeon: dont use get_engine_clock() on APUs
Date: Thu,  9 May 2013 15:34:28 -0700	[thread overview]
Message-ID: <20130509223423.927520868@linuxfoundation.org> (raw)
In-Reply-To: <20130509223422.368544659@linuxfoundation.org>

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

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

From: Alex Deucher <alexander.deucher@amd.com>

commit bf05d9985111f85ed6922c134567b96eb789283b upstream.

It doesn't work reliably.  Just report back the currently
selected engine clock.

Partially fixes:
