Right now, the DRM panel logic returns NULL when a panel pointing to the passed OF node is not present in the list of registered panels. Most drivers interpret this NULL value as -EPROBE_DEFER, but we are about to modify the semantic of of_drm_find_panel() and let the framework return -ENODEV when the device node we're pointing to has a status property that is not equal to "okay" or "ok". Let's first patch the of_drm_find_panel() implementation to return ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace the '!panel' check by an 'IS_ERR(panel)' one.
