[PATCH v2 13/27] drm/dp_mst: Refactor drm_dp_mst_handle_down_rep()
* Remove the big ugly have_eomt conditional
* Store &mgr->down_rep_recv.initial_hdr in a var to make line wrapping
easier
* Remove duplicate memset() calls
* Actually wrap lines

[PATCH v2 12/27] drm/dp_mst: Refactor drm_dp_mst_handle_up_req()
There's a couple of changes here, so to summarize:
* Remove the big ugly mgr->up_req_recv.have_eomt conditional to save on
indenting
* Store &mgr->up_req_recv.initial_hdr in a variable so we don't keep
going over 80 character long lines
* De-duplicate code for calling drm_dp_send_up_ack_reply() and getting
the MSTB via it's GUID
* Remove all of the duplicate calls to memset() and just use a goto
instead
* Actually do line wrapping
* Remove the unnecess...

[PATCH v2 00/27] DP MST Refactors + debugging tools + suspend/resume reprobing
This is the large series for adding MST suspend/resume reprobing that
I've been working on for quite a while now. In addition, I:
- Refactored and cleaned up any code I ended up digging through in the
process of understanding how some parts of these helpers worked.
- Added some debugging tools along the way that I ended up needing to
figure out some issues in my own code
