Merge tag 'pwrseq-fixes-for-v6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull power sequencing fixes from Bartosz Golaszewski:
"There's one fix for an invalid pointer dereference in error path
reported by smatch and two patches that address the noisy config
choices you reported earlier this week.

Summary:

- fix an invalid pointer dereference in error path in pwrseq core

- reduce the Kconfig noise from PCI pwrctl choices"

* tag 'pwrseq-fixes-for-v6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:
arm64: qcom: don't select HAVE_PWRCTL when PCI=n
Kconfig: reduce the amount of power sequencing noise
power: sequencing: fix an invalid pointer dereference in error path
