Subject: [PATCH 3.8-stable] regmap: irq: call pm_runtime_put in pm_runtime_get_sync
Date: Thu, 18 Apr 2013 08:25:52 +0900 [thread overview]
Message-ID: <003601ce3bc2$e72fd950$b58f8bf0$%choi@samsung.com> (raw)
In-Reply-To:
3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Li Fei <fei.li@intel.com>"
commit 283189d3be56aa6db6f192bb255df68493cd79ac upstream.
Even in failed case of pm_runtime_get_sync, the usage_count
is incremented. In order to keep the usage_count with correct
value and runtime power management to behave correctly, call
pm_runtime_put(_sync) in such case.
