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.
