Hi stable maintainers,

It seems that Linux kernel 4.19 and below miss the patch - "fbmem: add margin check to fb_check_caps()" [1]. Linux kernel 5.4 and up is already merged this patch[2].

Are there any special issues about this patch? Why do maintainers miss such a patch?

Because it does not apply to those older kernels. If you feel it should be included there, can you please provide a working backport of the patch so that we can apply it?

Sure, I will do that. Which mailing list or maintainers should I send to?

thanks,

greg k-h
