Any chances to get this into mainline with some priority?

If in your opinion the fix is not correct I can just send a revert of
the buggy commit.

I reported the bug 4 weeks ago, the same day the broken commit was
merged into -next [1], now we have a regression in mainline that is
preventing booting with a kernel panic and because of that our whole CI
is not able to test anything and therefore preventing us to look into
any other regression.

Thanks,
Francesco
