Description of problem:

When I install the latest kernel (5.14.0-274.el9.x86_64, and earlier ones too) with dnf, I get a message that compilation of evdi kernel module failed. The relevant section of /var/lib/dkms/evdi/1.12.0/build/make.log states:

In file included from /var/lib/dkms/evdi/1.12.0/build/evdi_connector.c:19:
/var/lib/dkms/evdi/1.12.0/build/evdi_drm_drv.h:31:10: fatal error: drm/drm_irq.h: No such file or directory
31 | #include <drm/drm_irq.h>

Then when I use that kernel, I get repeated messages in /var/log/messages that say:

Feb 26 00:27:28 localhost systemd[1]: Starting DisplayLink Driver Service...
Feb 26 00:27:28 localhost modprobe[8207]: modprobe: FATAL: Module evdi not found in directory /lib/modules/5.14.0-274.el9.x86_64
