Hello, With this patch linux-image-5.11.0-13-generic is not booting anymore a raspberry pi 4 with UEFI firmware (https://github.com/pftf/RPi4) (on hirsute)
I compiled from https://kernel.ubuntu.com/git/ubuntu/ubuntu-hirsute.git , without this patch, and the raspberry is booting Ok.

[Fix] Prevent the graphics device from being runtime suspended. [Test] With the patch applied, using efifb on graphics device without driver always work, because the device stays at D0 all the time. [Where problems could occur] Potentially this can affect power consumption, if user expects to put graphics device to D3cold, and is fine to get a broken efifb.
