Starting with commit 6b2117ad65f1 ("of: property: fw_devlink: Add
support for "resets" and "pwms""), the imx-drm driver fails to load
due to forever dormant devlinks to the reset-controller node. This
node is never associated with a struct device.

Drop those links, the reset controller is always available.

This deserves a Fixes tag, so that it can land in 5.15.

Will do.

Tested on a imx6dl-pico-pi board and after applying your patch the
display controller is probed, thanks:

Tested-by: Fabio Estevam <festevam@gmail.com>

However, I get the following warning:

Thank you. This does not happen on HDMI-only boards, but on Nitrogen6X
with LVDS panel I see the same.

Let's hold off this patch for a day or two please. I want to take a
closer look to see if I have a more generic fix.
