Summary (struct drm_encoder_helper_funcs)->mode_set not re-called after display (and EDID) change
Severity normal

I use my DCE5 Barts (HD69xx) with AV-receiver Onkyo TX-SR605 and one of the
following displays:
1) TV Sony Bravia KDL-52X3500
2) Projector Epson EH-TW6100

My problem is that when I change display connected to the Onkyo's output EDID
changes, but drm doesn't call mode_set as long as I use the same resolution.

To force drm to call mode_set I've to change resolution (xrandr --output HDMI-0
--mode X) and then swtich back to the mode I want.

While the display seems to be working fine without that mode_set call, the
audio engine doesn't. As part of the modesetting handler we read ELD-related
info from EDID and write it to the audio engine of the GPU. Without this
happening I can't play correctly audio (because also sees info about previous
device, not the current one).

I think mode_set should be called every time EDID changes. Is that right?
