| Subject: io: accel: kxcjk1013: restore the range after resume. |
| |
| 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. |
