Which tree do you plan to apply it to? I can put in drm-intel, and with the fixes tag it will percolate through to 5.3 and beyond, but if you want to apply it directly to squash the build warnings, feel free.
It would be nice to get it into 5.3. I can route it linuxwards if you give an Acked-by, but I'm happy to hand it to you :)

Thomas did you take this through tip tree after Chris' ACK?
Hi,
Gentle ping... Thomas and Chris: Will someone of you pick this up? As "objtool: Improve UACCESS coverage" [1] went trough tip tree I highly appreciate to do so with this one.
I think Thomas has gone on holiday, so hopefully Chris can pick it up after all.
tglx just picked up 2 other patches of mine, bumping just in case he's not picking up patches while on vacation. ;)
