I have a slightly uneasy feeling about handing out drm_panel pointers (both from here and of_drm_find_panel) without refcounting. If the panel driver gets removed, whoever called the find functions will have a dangling pointer. I supposed this will be discussed on drm-devel.
There's been some discussion already about exactly this problem (but with drm bridges) with Thierry and some other people. Cc'ed them all hopefully. Especially when the panel/bridge is a separate driver there's imo indeed an issue. -Daniel
