Thanks for the very quick reaction to this regression! However I think we
should fix it differently.

I had definitely build-tested most if not all these drivers, and also
runtime tested a few. Now I realized the build failure actually happens
only in !OF defconfigs which I haven't build-tested (sorry about
that!). Here's why:

 * the affected drivers (all or most of them) include drm_of.h
 * drm_of.h does:
     #if IS_ENABLED(CONFIG_OF) && IS_ENABLED(CONFIG_DRM_PANEL_BRIDGE)
     #include <linux/of.h>
     #include <drm/drm_bridge.h>
     #include <drm/drm_panel.h>
     #endif
 * DRM_PANEL_BRIDGE is always set when DRM is set, so not a problem
 * drivers which don't depend on OF and don't include drm_panel.h now fail

Most of the drivers changed by this patch do 'depend on OF', so they are
not affected. So the patch could be trimmed significantly. But still I'm
not in favor of including drm_panel.h in the remaining drivers, because:

 * in the first place most/all of these drivers are now supposed to not use
   the drm_panel API anymore; thsy should just use the drm_bridge API

 * devm_drm_of_get_bridge() is now a deprecated [0], complicated way of
   calling of_drm_get_bridge_by_endpoint(), which is rightfully in
   drm_bridge.h
   * for this reason Documentation/drm/todo.rst says it must be removed [1]
   * removal is easy, so I plan to do it in a few weeks globally
   * after the removal all these #include <drm_panel.h> would have to
     be removed, but some might easily be forgotten

So I see two option for a better fix:

 * Option 1 -- fix the really affected drivers by switching from the
   deprecated API to the one they recommended one. Based on quick analysis
   there are about 6.

 * Option 2 -- a quick surgical fix:

   In drm_of.h:

     #if IS_ENABLED(CONFIG_OF) && IS_ENABLED(CONFIG_DRM_PANEL_BRIDGE)
      #include <linux/of.h>
      #include <drm/drm_bridge.h>
     -#include <drm/drm_panel.h>
      #endif
     +#include <drm/drm_panel.h> /* Temporary for *_of_get_bridge() */

   This can easily be tracked and reverted once all
   devm_drm_of_get_bridge() users are converted to
   of_drm_get_bridge_by_endpoint().

I'm working right now on option 1, hoping to get a series in a few hours
from now. I can switch to option 2 in case of unexpected issues with option
1, or if a fix "really right now" is wanted.
