Subject: drm/mgag200: Index 24 in extended CRTC registers is 24 in hex, not
decimal.
From: Christopher Harvey <[email protected]>
commit 1812a3db0874be1d1524086da9e84397b800f546 upstream.
This change properly enables the "requester" in G200ER cards that is
responsible for getting pixels out of memory and clocking them out to
the screen.
