The following commit has been merged into the irq/irqchip-next branch of irqchip: Commit-ID: f9ee20c85b3a3ba0afd3672630ec4f93d339f015 Gitweb: https://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms/f9ee20c85b3a3ba0afd3672630ec4f93d339f015 Author: Shang XiaoJing <shangxiaojing@huawei.com> AuthorDate: Thu, 24 Nov 2022 14:51:50 +08:00 Committer: Marc Zyngier <maz@kernel.org> CommitterDate: Sat, 26 Nov 2022 13:29:42 irqchip: gic-pm: Use pm_runtime_resume_and_get() in gic_probe() gic_probe() calls pm_runtime_get_sync() and added fail path as rpm_put to put usage_counter. However, pm_runtime_get_sync() will increment usage_counter even it failed. Fix it by replacing it with pm_runtime_resume_and_get() to keep usage counter balanced.
