[PATCH 19/21] exynos_tmu: use devm_irq_of_parse_and_map()

From: nyushchenko
Date: Wed Jun 04 2014 - 07:38:48 EST


From: Nikita Yushchenko <nyushchenko@xxxxxxxxxxxxx>

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.
