Subject: [PATCH 17/21] PCI: imx6: Use common mask in imx6_pcie_reset_phy()
Date: Thu, 20 Dec 2018 23:27:12 -0800 [thread overview]
Message-ID: <20181221072716.29017-18-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20181221072716.29017-1-andrew.smirnov@gmail.com>
Simplify imx6_pcie_reset_phy() by using common mask. No functional
change intended.
