One of the quirks that we introduced to build with !ACPI && COMPILE_TEST
throws the following smatch warning:
drivers/media/pci/intel/ipu-bridge.c:752 ipu_bridge_ivsc_is_ready() warn: iterator 'i' not incremented
Fix it by replacing the condition.

The better would be to just remove all #if and handle ACPI compatibility
with COMPILE_TEST inside acpi headers.
Besides that, t sounds that patch 2 makes this hack unneeded, as you added
a false check at the for macro:
#define for_each_acpi_dev_match(adev, hid, uid, hrv) \
for (adev = NULL; false && (hid) && (uid) && (hrv);)
Please place only one set of subsystem maintainers at the To: line,
directing to the one(s) you expect to merge this series.
In this particular case, the one to be added should be the ACPI
maintainers.

Mauro

The plan was to land 1/7 via the media tree with a PR from Sakari soonish.
I believe he has already picked it on his tree. I will remove you from
Cc in the next version
thanks :)

I prefer not merging it via media tree, except if we get an explicit ack to do so from ACPI maintainers, as most of the stuff here are at ACPI headers. Thanks, Mauro

Thanks! If you do not mind, I will keep sending 1/7 when I send v3, to make sure it is tested by the CI. I will mark it as duplicate in patchwork.

I will mark it as duplicate in patchwork. Patches should not be designed to make CI happy, but to ensure that we have a nice history at Kernel's log. Patch 1/7 shall be merged with 7/7, as you're just artificially breaking it into without a good reason, making CI happy, but reviewers and maintainers unhappy :-) Thanks, Mauro
