Subject: [PATCH V2 28/28] PCI: tegra: Change link retry log level to info
Date: Tue, 23 Apr 2019 14:58:25 +0530	[thread overview]
Message-ID: <20190423092825.759-29-mmaddireddy@nvidia.com> (raw)
In-Reply-To: <20190423092825.759-1-mmaddireddy@nvidia.com>

Driver checks for link up three times before giving up, each retry attempt
is printed as an error. Letting users know that PCIe link is down and in the
process of being brought up again is informational, not an error condition.
