Subject: [PATCH v2 1/6] usb: gadget: udc: renesas_usb3: fix double phy_put()
Date: Tue, 10 Apr 2018 14:38:49 +0900	[thread overview]
Message-ID: <1523338734-20474-2-git-send-email-yoshihiro.shimoda.uh@renesas.com> (raw)
In-Reply-To: <1523338734-20474-1-git-send-email-yoshihiro.shimoda.uh@renesas.com>

This patch fixes an issue that this driver cause double phy_put()
calling. This driver must not call phy_put() in the remove because
the driver calls devm_phy_get() in the probe.
