[PATCH v2 06/27] drm/dp_mst: Combine redundant cases in drm_dp_encode_sideband_req()
Noticed this while working on adding a drm_dp_decode_sideband_req(). DP_POWER_DOWN_PHY/DP_POWER_UP_PHY both use the same struct, so we can just combine their cases.

[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 Note that
