[PATCH 4/4] drm/virtio: Use IDAs more efficiently

Uh. This line is missing.
- int handle = ida_alloc_min(&vgdev->ctx_id_ida, 1, GFP_KERNEL);
+ int handle = ida_alloc(&vgdev->ctx_id_ida, GFP_KERNEL);
It'll be there in v2 ;-)

[PATCH 0/4] Improve virtio ID allocation
I noticed you were using IDRs where you could be using the more efficient
IDAs, then while fixing that I noticed the lack of error handling,
and I decided to follow that up with an efficiency improvement.
There's probably a v2 of this to follow because I couldn't figure
out how to properly handle one of the error cases ... see the comment
embedded in one of the patches.

I've touched the resource/object id handling too, see my "drm/virtio:
