Subject: linux-next: build failure after merge of the pmdomain tree
Hi all,
After merging the pmdomain tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

cc1: some warnings being treated as errors
Caused by commit
df4e9ec1ed86 ("pmdomain: mediatek: Add support for secure HWCCF infra power on")
(and maybe others)
I have used the pmdomain tree from next-20251022 for today.
