Subject: [PATCH v1 08/16] rtc: mediatek: remove unnecessary irq_dispose_mapping
Date: Fri, 23 Mar 2018 17:15:05 +0800	[thread overview]
Message-ID: <96f39ce7f57a4dcd7653e049eebc87c83bcbdfc9.1521794177.git.sean.wang@mediatek.com> (raw)
In-Reply-To: <cover.1521794176.git.sean.wang@mediatek.com>

From: Sean Wang <sean.wang@mediatek.com>

It's unnecessary doing irq_dispose_mapping as a reverse operation for
platform_get_irq.

Ususally, irq_dispose_mapping should be called in error path or module
removal to release the resources for irq_of_parse_and_map requested.
