From mboxrd@z Thu Jan 1 00:00:00 1970 From: Florian Fainelli Subject: [PATCH net-next] net: phy: phylink: Don't release NULL GPIO Date: Sun, 20 May 2018 20:49:47 -0700 Message-ID: <20180521034947.469-1-f.fainelli@gmail.com> Cc: rmk+kernel@armlinux.org.uk, Florian Fainelli , Andrew Lunn , "David S. Miller" , linux-kernel@vger.kernel.org (open list) To: netdev@vger.kernel.org Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org If CONFIG_GPIOLIB is disabled, gpiod_put() becomes a stub that produces a warning, this helped identify that we could be attempting to release a NULL pl->link_gpio GPIO descriptor, so guard against that.
