In function _hid_sensor_power_state(), when hid_sensor_read_poll_value() is called, sensor's all properties will be updated by the value from sensor hardware/firmware. In some implementation, sensor hardware/firmware will do a power cycle during S3. In this case, after resume, once hid_sensor_read_poll_value() is called, sensor's all properties which are kept by driver during S3 will be changed to default value. But instead, if a set feature function is called first, sensor hardware/firmware will be recovered to the last status. So change the sensor_hub_set_feature() calling order to behind of set feature function to avoid sensor properties lose.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
