drm/imagination: Fixes for power domain handling on single-domain devices

[PATCH 0/3] drm/imagination: Fixes for power domain handling on single-domain devices

Posted by Matt Coster 1 month, 1 week ago

The first patch here fixes the exact issue reported by Mark in the
linked issue. The remaining patches are related foot-gun-like issues
that were discovered in the process.

Although entirely fixes, this series is targetting drm-misc-next since
the underlying commit e19cc5ab347e ("drm/imagination: Use
dev_pm_domain_attach_list()") does not yet exist in any other trees (to
the best of my knowledge).

      drm/imagination: Check for NULL struct dev_pm_domain_list
      drm/imagination: Detach pm domains if linking fails
      drm/imagination: Ensure struct pvr_device->power is initialized
