From mboxrd@z Thu Jan 1 00:00:00 1970 From: Grygorii Strashko Subject: [PATCH] input: serio: drop warnings in case of EPROBE_DEFER from serio_find_driver() Date: Fri, 15 Jan 2016 20:01:15 +0200 Message-ID: <1452880875-4148-1-git-send-email-grygorii.strashko@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Dmitry Torokhov Cc: linux-input@vger.kernel.org, nsekhar@ti.com, linux-kernel@vger.kernel.org, lkp@01.org, Grygorii Strashko , "Rafael J . Wysocki" List-Id: linux-input@vger.kernel.org Now serio_find_driver() will print warnings in case device_attach() returns -EPROBE_DEFER. Those warnings are obsolete, in genral, because: - DD core can report the same if required - since commit 013c074f8642 ("PM / sleep: prohibit devices probing during suspend/hibernation") the devices probing is prohibited during System suspend and deferred device will be carefully reprobed once Resume is finished. Hence, drop warnings in case of EPROBE_DEFER from serio_find_driver(). Cc: Dmitry Torokhov Cc: Rafael J.
