The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

I slightly prefer them separately, because I like small patches and
because the Acks and Reviews only apply to the individual drivers.
But I don't mind seriously, so here comes the series squashed into one.
While going through the changed, probably the s3c24xx driver (which
isn't exactly identical to the other changes) could benefit from an
additional change throwing out the early exit (which---I guess---cannot
be hit).
BTW, I constructed the lists of acks/reviews myself and found the same
set. However b4 wailed about each patch claiming:
✗ BADSIG: DKIM/infradead.org
And it didn't like you producing the tags, saying:
