The commit 8c493cc91f3a ("PCI/pwrctrl: Create pwrctrl devices only when CONFIG_PCI_PWRCTRL is enabled") introduced a typo, it uses CONFIG_PCI_PWRCTRL while the correct symbol is CONFIG_PCI_PWRCTL. As reported by Daniel Martin, it causes device initialization failures on some arm boards. I encountered it on sm8250-xiaomi-pipa after rebasing from v6.15.8 to v6.15.11, with the following error: [ 6.035321] pcieport 0000:00:00.0: Failed to create device link (0x180) with supplier qca6390-pmu for /soc@0/pcie@1c00000/pcie@0/wifi@0
Fix the typo to use the correct CONFIG_PCI_PWRCTL symbol.

Might this be a stale .config file?
I think 13bbf6a5f065 ("PCI/pwrctrl: Rename pwrctrl Kconfig symbols and slot module") should have resolved this.
In the current upstream tree (fd94619c4336 ("Merge tag 'zonefs-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs"), git grep "<CONFIG_PCI_PWRCTL>" finds nothing at all.
