[PATCH 0/4] drm unplugging docs

[Daniel Vetter]

Hi all,

Just a small cleanup plus kerneldoc for the unplug support. There's still the
fundamental problem that most likely our lifetime stuff is entirely screwed up
for this, at least never export a dma-buf or dma-fence from a driver which can
be hot-unplugged.

It'd be sweet if we could properly fix this by attaching resources to either the
physical device (which should be drm_device->dev) or the sw device (aka
drm_device) depending upon whether it is needed after unplugging. There's also
the slight problem of synchronizing all that access somehow.

Either way this is a separate topic, I just thought about it a bit more while
cleaning this up.

On the patches themselves: I had to move struct drm_device into drm_device.h to
avoid a header include loop, since that's a bit invasive it'd be great if I can
land this fast.

Cheers, Daniel
