Subject: [PATCH 09/21] apbps2: use devm_irq_of_parse_and_map()
Date: Wed, 4 Jun 2014 15:13:09 +0400 [thread overview]
Message-ID: <1401880402-30091-10-git-send-email-nyushchenko@dev.rtsoft.ru> (raw)
In-Reply-To: <1401880402-30091-1-git-send-email-nyushchenko@dev.rtsoft.ru>
From: Nikita Yushchenko <nyushchenko@dev.rtsoft.ru>
This avoids leak of IRQ mapping on error paths, and makes it possible
to use devm_request_irq() without facing unmap-while-handler-installed
issues.
