Subject: [PATCH v7 01/14] PCI: cadence: Fix cdns_pcie_{host|ep}_setup() error path
Date: Mon, 13 Jul 2020 16:31:28 +0530	[thread overview]
Message-ID: <20200713110141.13156-2-kishon@ti.com> (raw)
In-Reply-To: <20200713110141.13156-1-kishon@ti.com>

commit bd22885aa188 ("PCI: cadence: Refactor driver to use as a core
library") while refactoring the Cadence PCIe driver to be used as
library, removed pm_runtime_get_sync() from cdns_pcie_ep_setup()
and cdns_pcie_host_setup() but missed to remove the corresponding
pm_runtime_put_sync() in the error path. Fix it here.
