Subject: drm/nv40/mpeg: write magic value to channel object to make it work
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3d8b2b489e490ae63b7eddb3dcdfcee9bc32d473;p=openwrt%2Fstaging%2Fblogic.git

drm/nv40/mpeg: write magic value to channel object to make it work

Looks like the rewrite in commit ebb945a94b ("drm/nouveau: port all
engines to new engine module format") missed that one little detail.
