Subject: [PATCH 2/4] iio: hid-sensor-trigger: Decrement runtime pm enable count on driver removal
Date:   Thu, 19 Nov 2020 11:03:24 +0800
Message-Id: <20201119030326.6447-3-xiang.ye@intel.com>
In-Reply-To: <20201119030326.6447-1-xiang.ye@intel.com>
References: <20201119030326.6447-1-xiang.ye@intel.com>
Precedence: bulk

To avoid pm_runtime_disable called repeatedly by hid sensor drivers,
decrease runtime pm enable count after call it.
