Subject: [PATCH v7 1/2] PCI: cadence: Shifting of a function to support new code.
Date: Wed, 30 Dec 2020 13:05:14 +0100	[thread overview]
Message-ID: <20201230120515.2348-2-nadeem@cadence.com> (raw)
In-Reply-To: <20201230120515.2348-1-nadeem@cadence.com>

Move the function cdns_pcie_host_wait_for_link() further up in the file,
as it's going to be used by upcoming additional code in the driver.
