Subject[PATCH 4.9 017/105] drm/nouveau/disp/nv50-: bump max chans to 21
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

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

From: Ilia Mirkin <imirkin@alum.mit.edu>

commit a90e049cacd965dade4dae7263b4d3fd550e78b6 upstream.

GP102's cursors go from chan 17..20. Increase the array size to hold
their data properly.

Fixes: e50fcff15f ("drm/nouveau/disp/gp102: fix cursor/overlay immediate channel indices")
