Subject: [PATCH v3 RESEND 01/35] drm: Remove drm_bridge->dev
As suggested in [1], the 'dev' field is a bit repetitive, since it 1:1
follows the setting and NULLing of the 'encoder' field. Therefore, use
drm_bridge->encoder->dev in place of drm_bridge->dev.
[1] https://patchwork.freedesktop.org/patch/343824/
v3:
- resend as part of drm_bridge_init() series
v2:
- fix checkpatch complaint about unnecessary parentheses in
drm_bridge.c
Cc: Daniel Vetter <daniel@...ll.ch>
