[PATCH 0/2] Fix the shutdown callback of a drm component device

Posted by Heiko Stuebner 9 months, 4 weeks ago

Probe deferral can cause the platform-data we access to be freed already
causing ugly splats on system shutdown.

Fix this via a small component-helper and adapting the rockchip-drm
shutdown handler.

  drivers: base: component: add function to query the bound status
  drm/rockchip: Fix shutdown when no drm-device is set up
