I should edit the zero day bot emails to send the correct link. That's going to be slightly more complicated than you might assume... I'm travelling now so I won't do it today. regards, dan carpenter > > Fixes: 0578a6dbfe75 ("spi: spi-cadence-quadspi: add runtime pm support") > Reported-by: kernel test robot <lkp@intel.com> > Reported-by: Dan Carpenter <dan.carpenter@linaro.org> > Closes: https://lore.kernel.org/r/202309140543.03dMbMM5-lkp@intel.com/ > Signed-off-by: Dhruva Gole <d-gole@ti.com> > --- > > Link to V1: > https://lore.kernel.org/all/20230915123103.2493640-1-d-gole@ti.com/ >

OK, will rebase and send along with the fixed closes tag.

Pardon, which branch is this being applied on? I am on the following base and it applies OK: commit b643e6268c8f466ebb08a594b8ec8a1e2fd275a2 (spi-broonie/for-next) Merge: 3b4e5194138b da6de6d3ecc1 Author: Mark Brown <broonie@kernel.org> Date: Tue Sep 26 13:08:30 2023 +0200 Merge remote-tracking branch 'spi/for-6.7' into spi-next origin: spi-broonie https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git

It'll have been applied as a fix so against 6.6.

Umm I don't think the commit being fixed is there in 6.6? I am not really sure how I should base/format the patch? Please can you tell me what's expected in such a case ideally?

Please can you > tell me what's expected in such a case ideally? Including a full 12 character commit hash would help with matching, there were only 10 there. Not mix'n'matching Link:/Close: with links in the body of the commit message would help as well.

OK, I have fixed the links and sent the patch V3 Again, I have based on your for-next, as I don't see the fixes: commit in the 6.6 tree.

[1/1] spi: spi-cadence-quadspi: Fix missing unwind goto warnings commit: 86401132d7bbb550d80df0959ad9fa356ebc168d 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
