linux-next: build failure after merge of the pmdomain-fixes tree

[Mark Brown]

Hi all,

After merging the pmdomain-fixes tree, today's linux-next build
(arm multi_v7_defconfig) failed like this:

AFAICT this is caused by commit

   d7262971a2acc (pmdomain: imx: gpc: remove all initialized power domains)

though I don't really see how.  I have used the tree from next-20261109
instead.
