Alternatively to my additional patch sent earlier today I prepared a v2 tag at https://git.pengutronix.de/git/ukl/linux tags/amba-make-remove-return-void-v2 with the build fix squashed in. Iff you prefer and both Russell and Greg agree to pull this one instead of the (implicit) v1 we can maybe prevent introducing this build regression in mainline. Please coordinate among you two. And sorry again for breaking the build.

I took v1, and put it in a branch I've promised in the past not to rebase/rewind. Uwe is now asking for me to take a v2 or apply a patch on top. The only reason to produce an "immutable" branch is if it's the basis for some dependent work and you need that branch merged into other people's trees... so the whole "lets produce a v2" is really odd workflow... I'm confused about what I should do, and who has to be informed which option I take. I'm rather lost here too.

After I saw that my initial tag missed to adapt a driver I wanted to make it easy for you to fix the situation. So I created a patch to fix it and created a second tag with the patch squashed in. Obviously only one of them have to be picked and I hoped you (= Russell + Greg) would agree which option to pick. My preference would be if you both pick up v2 of the tag to yield a history that is bisectable without build problems, but if Russell (who already picked up the broken tag) considers his tree immutable and so isn't willing to rebase, then picking up the patch is the way to go. I suggest that Russell descides which option he wants to pick and tells Greg to do the same!? Best regards Uwe

OK, the current state is that Russell applied the patch fixing drivers/mailbox/arm_mhuv2.c on top of merging my first tag. So the way forward now is that Greg pulls git://git.armlinux.org.uk/~rmk/linux-arm.git devel-stable which currently points to 860660fd829e ("ARM: 9055/1: mailbox: arm_mhuv2: make remove callback return void") , into his tree that contains the hwtracing changes that conflict with my changes. @Greg: Is this good enough, or do you require a dedicated tag to pull that? I think these conflicting hwtracing changes are not yet in any of Greg's trees (at least they are not in next). When I pull https://git.kernel.org/pub/scm/linux/kernel/git/coresight/linux.git next (currently pointing to 4e73ff249184 ("coresight: etm4x: Handle accesses to TRCSTALLCTLR")) into 860660fd829e, I get a conflict in drivers/hwtracing/coresight/coresight-etm4x-core.c as expected. My resolution looks as follows: diff --cc drivers/hwtracing/coresight/coresight-etm4x-core.c index 82787cba537d,5017d33ba4f5..000000000000 --- a/drivers/hwtracing/coresight/coresight-etm4x-core.c +++ b/drivers/hwtracing/coresight/coresight-etm4x-core.c @@@ -1703,6 -1906,28 +1906,27 @@@ static int __exit etm4_remove_dev(struc cpus_read_unlock(); coresight_unregister(drvdata->csdev); + + return 0; + } + -static int __exit etm4_remove_amba(struct amba_device *adev) ++static void __exit etm4_remove_amba(struct amba_device *adev) + { + struct etmv4_drvdata *drvdata = dev_get_drvdata(&adev->dev); + + if (drvdata) - return etm4_remove_dev(drvdata); - return 0; ++ etm4_remove_dev(drvdata); + } + + static int __exit etm4_remove_platform_dev(struct platform_device *pdev) + { + int ret = 0; + struct etmv4_drvdata *drvdata = dev_get_drvdata(&pdev->dev); + + if (drvdata) + ret = etm4_remove_dev(drvdata); + pm_runtime_disable(&pdev->dev); + return ret; } static const struct amba_id etm4_ids[] = { Best regards Uwe

I looked at https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git char-misc-testing commit 0573d3fa48640f0fa6b105ff92dcb02b94d6c1ab now. I didn't compile test, but I'm willing to bet your resolution is wrong. You have no return statement in etm4_remove_dev() but its return type is int and etm4_remove_amba() still returns int but should return void. Best regards Uwe

Can you send a patch to fix this up? thanks, greg k-h
Hello, the following changes since commit 5c8fe583cce542aa0b84adc939ce85293de36e5e: Linux 5.11-rc1 (2020-12-27 15:30:22 -0800) are available in the Git repository at: https://git.pengutronix.de/git/ukl/linux tags/amba-make-remove-return-void for you to fetch changes up to f170b59fedd733b92f58c4d7c8357fbf7601d623: amba: Make use of bus_type functions (2021-02-02 14:26:02 +0100) I expect this tag to be merged by Russell King as amba maintainer and by Mathieu Poirier (or Greg Kroah-Hartman?) for coresight as there are some pending conflicting changes. These are not hard to resolve but also non-trivial. Tell me if you need assistance for resolving, also if it's only a second pair of eyes to judge your resolution.
