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?
If I have any misunderstanding, please let me know.

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?
thanks,

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