Patch for 5.4(https://lore.kernel.org/stable/163757721744154@kroah.com/) and 5.10(https://lore.kernel.org/stable/1637577215186161@kroah.com/) are failed to apply.

Thanks, LGTM.
I think it would be better to add the comment of the conflict fixing.
e.g. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.10.y&id=1ada86999dc84b852fcc32962f4002e939f4beb7

Best regards,
