Subject: [PATCH v2 11/11] pci: dwc: pcie-kirin: cleanup kirin970_pcie_get_eyeparam()
Date: Wed,  3 Feb 2021 08:01:55 +0100
Message-ID: <1584b35df936f50bb3187c233b9110c53652a518.1612335031.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1612335031.git.mchehab+huawei@kernel.org>

Cleanup the routine, to let it clearer that eye_param is optional and
that, if not specified, the driver will assume the default.

While here, also drop the useless debug prints.
