3.6.11.6 stable review patch.
If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher@xxxxxxx>
[ Upstream commit 09fb8bd1a63b0f9f15e655c4fe8d047e5d2bf67a ]
Newer asics have variable numbers of crtcs. Use that
rather than the asic family to determine which crtcs
to check. This avoids checking non-existent crtcs or
missing crtcs on certain asics.
