This is not upstream or against an mm tree. Against which tree is it?

The fix for this issue has been squashed into commit 0fd17e598333 ("of:
reserved_mem: Allow reserved_mem framework detect "cma=" kernel param")
and merged to v6.19-rc8, so the above fix is not longer needed.

Ah, that's just what I wanted to ask: can this be squashed :)

Thanks!
