Subject: [PATCH 1103/1135] drm/bridge: panel: Name an associated backlight
|
||
|
device
|
||
|
|
||
|
Pass the DRM connector name to any configured backlight
|
||
|
device so that userspace can associate the two items.
|
||
|
|
||
|
Ideally this should be in drm_panel, but it is bridge/panel
|
||
|
that creates the drm_connector and therefore knows the name.
