Subject: [PATCH v3 02/11] PCI: imx6: Remove redundant debug tracing
Date: Sun, 31 Mar 2019 21:25:38 -0700 [thread overview]
Message-ID: <20190401042547.14067-3-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190401042547.14067-1-andrew.smirnov@gmail.com>
All calls to imx6_pcie_wait_for_link() share the same error path and
the state of PHY debug registers will already be printed there.
