dmesg text

Found a "Bogus possible_crtcs" warning in a new build of kernel 5.8.5 see attached dmesg log. Is this something to be concerned about ?

possible fix

The warning is harmless, but I think this patch should fix it.
Comment 2 Stuart Foster 2020-12-04 13:32:08 UTC
That seems to fix the problem, tested it on kernels 5.8.7 and 5.9.10.

thank you Alex.
