Subject: [PATCH v2 4/5] amba: Make the remove callback return void
From: Uwe Kleine-König <u.kleine-koenig@...gutronix.de>
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.
