Hi all,
So this is the second iteration of my connector locking series. This tries to
clarify the cargo-culted locking rules around hotadd/removing drm_connector,
which was added to support DP MST. I want to get this in first for a release or
so just to document all the locking rules we have (and make sure there's no
callchain that I've forgotten) before trying to rework the connector lifetime
handling to not require massive amounts of locks and block everything in
hotadd/remove.
Changes to last time around:
- Now with radeon!
- No hotplug for encoders, so no locking WARNINGs for those (Dave).
- A bit of polish all over.
- Thrown in the mode_group removal for good measure (but that one's really not
related to this, only noticed it while reading around code).
Feedback, review and comments highly welcome!
Cheers, Daniel
