Kernel 6.6 had removed the FBINFO_DEFAULT. I will fix it and feed back to you~

[bigbearishappy]

@mirkokral Have you tried to fix this error by yourself? If not, I will have a try to fix it.

[bigbearishappy]

I did a quick fix in here and it works fine now.

currently cant try it as neither of my 2 rpis (a 4 and a 5) are working

[bigbearishappy]

I tried it with my raspberrypi CM4 and it work fine~

try upgrading your kernel, but for me downgrading to kernel ver 5 worked

[bigbearishappy]

Sounds good. Please let me know if you have problem with upgrading to linux kernel 6.
