From 3fd269e74f2feec973f45ee11d822faeda4fe284 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Tue, 26 Jan 2021 17:58:34 +0100 Subject: amba: Make the remove callback return void MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All amba drivers return 0 in their remove callback. Together with the driver core ignoring the return value anyhow, it doesn't make sense to return a value here. Change the remove prototype to return void, which makes it explicit that returning an error value doesn't work as expected. This simplifies changing the core remove callback to return void, too.
