Subject: [PATCH 3/3] phy: cpcap-usb: Drop extra write to usb2 register
Date: Sun, 22 Dec 2019 10:17:04 -0800	[thread overview]
Message-ID: <20191222181704.61511-3-tony@atomide.com> (raw)
In-Reply-To: <20191222181704.61511-1-tony@atomide.com>

We are currently writing the same register twice. Let's enable the USB
PHY only at the end of the function.
