Commit Message

Mihail Atanassov Dec. 24, 2019, 5:34 p.m. UTC 
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
