Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next Thanks! [1/1] ASoC: imx-hdmi: Fix warning of the uninitialized variable ret commit: acd894aee3149c15847bc4f0690fccba59ced5e7 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark

It is a regression fix, seems like it should. Cheers, Nathan

This is the first indication I've seen that anyone is seeing it in mainline, in general the people who report and fix warnings are doing so based on -next and the patch seems to be from a month ago. I don't have this in my inbox so I assume it's applied already or needs to be resubmitted anyway.

I have had plenty of my compiler warning patches sent as bug fixes for an -rc. Furthermore, this patch was sent three times by different people, that should give you some indication that people are tripping over it. https://lore.kernel.org/alsa-devel/X9NGQaF4pmK8oUAF@mwanda/ https://lore.kernel.org/alsa-devel/1608115464-18710-1-git-send-email-shengjiu.wang@nxp.com/ https://lore.kernel.org/alsa-devel/20201230154443.656997-1-arnd@kernel.org/ The first version was sent on December 11th, it looks like your pull for 5.11 went on the December 14th, then the second version was applied on December 16th so I figured it might be destined for 5.11 but I could not tell (your for-next branch is a merge of your for-5.11 and for-5.12): https://lore.kernel.org/alsa-devel/160813397775.31838.8934909997692637790.b4-ty@kernel.org/ Cheers, Nathan

I really don't have that good a recall of what warning fixes people are sending, I might notice if I get two versions of the same thing that I look at at roughly the same time but even with a few hours between it's most likely that I'll have completely forgotten. Warning fixes are in general not memorable, it's not a good sign if they are. The default assumption for any warning fix that doesn't say anything else is going to be that either the issue or the toolchain is very new. For any kind of fix if you think that things are in some way urgent you should say something promptly (or provide some indication of this in the submission if you're sending the fix yourself, such as with a fixes tag). If nobody says anything then you should assume that nobody else is going to be aware of any urgency and that this will affect handling. Should it happen that things aren't flagged up then of course do so but consider that this may well be the first time people will be aware there's any urgency, don't assume that people will have been operating with information they didn't have. > The first version was sent on December 11th, it looks like your pull for > 5.11 went on the December 14th, then the second version was applied on > December 16th so I figured it might be destined for 5.11 but I could not > tell (your for-next branch is a merge of your for-5.11 and for-5.12): If it's on the for-5.11 branch then it will be for 5.11, which it must be if it was applied then. If it was and it was applied that long ago it'll already be queued in Takashi's tree and I guess he didn't send it on yet.
