Subject: [patch 32/86] gpio: uniphier: utilize for_each_set_clump8 macro
Date: Wed, 04 Dec 2019 16:51:25 -0800 [thread overview]
Message-ID: <20191205005125.yDX3YQn8H%akpm@linux-foundation.org> (raw)
In-Reply-To: <20191204164858.fe4ed8886e34ad9f3b34ea00@linux-foundation.org>
From: William Breathitt Gray <vilhelm.gray@gmail.com>
Subject: gpio: uniphier: utilize for_each_set_clump8 macro
Replace verbose implementation in set_multiple callback with
for_each_set_clump8 macro to simplify code and improve clarity. An
improvement in this case is that banks that are not masked will now be
skipped.
