Subject: [PATCH V6 19/27] PCI: tegra: Change PRSNT_SENSE IRQ log to debug
Date: Tue, 18 Jun 2019 23:31:58 +0530
Message-ID: <20190618180206.4908-20-mmaddireddy@nvidia.com> (raw)
In-Reply-To: <20190618180206.4908-1-mmaddireddy@nvidia.com>

PRSNT_MAP bit field is programmed to update the slot present status.
PRSNT_SENSE IRQ is triggered when this bit field is programmed, which is
not an error. Add a new if condition to trap PRSNT_SENSE code and print it
with debug log level.
