From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lars-Peter Clausen Subject: [PATCH 4/4] tty: ifx6x60: Remove unused suspend/resume callbacks Date: Mon, 11 Mar 2013 18:44:52 +0100 Message-ID: <1363023892-15957-4-git-send-email-lars@metafoo.de> References: <1363023892-15957-1-git-send-email-lars@metafoo.de> Return-path: In-Reply-To: <1363023892-15957-1-git-send-email-lars@metafoo.de> Sender: linux-kernel-owner@vger.kernel.org To: Greg Kroah-Hartman Cc: linux-serial@vger.kernel.org, linux-kernel@vger.kernel.org, Lars-Peter Clausen , Bi Chao , Chen Jun List-Id: linux-serial@vger.kernel.org The ifx6x60 driver implements both legacy suspend/resume callbacks and dev_pm_ops. The SPI core is going to ignore legacy suspend/resume callbacks if a driver implements dev_pm_ops. Since the legacy suspend/resume callbacks are empty in this case it is safe to just remove them.
