From mboxrd@z Thu Jan 1 00:00:00 1970 From: Johan Hovold Subject: [PATCH 3/6] mfd: core: add helper function to register hotplug devices Date: Fri, 26 Sep 2014 12:55:30 +0200 Message-ID: <1411728933-13351-4-git-send-email-johan@kernel.org> References: <1411728933-13351-1-git-send-email-johan@kernel.org> Return-path: In-Reply-To: <1411728933-13351-1-git-send-email-johan@kernel.org> Sender: linux-kernel-owner@vger.kernel.org To: Samuel Ortiz , Lee Jones Cc: Jiri Kosina , linux-input@vger.kernel.org, Greg Kroah-Hartman , linux-kernel@vger.kernel.org, linux-usb@vger.kernel.org, Johan Hovold List-Id: linux-input@vger.kernel.org Hot-pluggable multi-function devices should always be registered with PLATFORM_DEVID_AUTO to avoid name collisions on the platform bus. This helper also hides the memory map and irq parameters, which aren't used by hot-pluggable (e.g. USB-based) devices.
