Do you see a stable tag? Is 5.19-stable still active? Why do you refer to activeness of v5.19? This will go also to v6.0 and v6.1. > > The problem is that the driver was updated before the binding was so the > above mentioned probe error has been there since this file was merged. I grepped and that commit did not have such compatible. Are you saying that the kernel which was released with this commit already had that compatible in driver (through different merge/tree)? > > AUTOSEL is crazy and people apparently just ignore it instead of NAKing > when it is suggesting backporting devicetree cleanups (which to be fair > should generally not have Fixes tags in the first place). Sorry, no clue what do you want to say here... if you are unhappy with AUTOSEL, I am not the one to receive such feedback. Anyway, regardless of AUTOSEL, my concern was that the release containing that commit was not ready to work with that compatible. Isn't this the case here? > > If 5.19-stable was still active and someone suggested backporting this Whether v5.19 is active or not, it does not matter. Why would it matter?

Note that that would need to happen regardless > of whether this patch has a Fixes tag or not. Any manual backporting of something which is not a fix for older kernel is already risky business and whoever is doing it, he is responsible for the outcome. Best regards, Krzysztof
