[PATCH 4.9 22/44] io: accel: kxcjk1013: restore the range after resume.

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: he, bo <bo.he@intel.com>

commit fe2d3df639a7940a125a33d6460529b9689c5406 upstream.

On some laptops, kxcjk1013 is powered off when system enters S3. We need
restore the range regiter during resume. Otherwise, the sensor doesn't
work properly after S3.
