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.
