Subject: [PATCH 16/21] PCI: imx6: Pass data to dw_pcie_writel_dbi() directly
Date: Thu, 20 Dec 2018 23:27:11 -0800 [thread overview]
Message-ID: <20181221072716.29017-17-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20181221072716.29017-1-andrew.smirnov@gmail.com>
Save a couple of lines of code by dropping assignement to 'var' and
passing constants as via function arguments directly. No functional
change intended.
