evdi-dkms fails to build with kernel 5.15

[Ludovico Massaccesi]

Attempting to install the evdi-dkms package with apt on hirsute results in the following error.

From /var/lib/dkms/evdi/1.9.1/build/make.log it appears that the drm_irq.h header is missing (this was actually present with kernel 5.11, but is not found in any of the newer linux-headers packages).

It would seem that this bug was reported on the evdi github repo as well

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.
