[PATCH] io: accel: kxcjk1013: restore the range after resume.

From: He, Bo
Date: Wed Feb 20 2019 - 22:13:51 EST


restore the range register in case kxcjk1013 power is off after suspend

we see the issue on some laptops, after system suspend and resume,
the CTRL_REG1 register changed from 0xc8 to 0x80, so acceleration range
is changed, the patch is to restore the acceleration range after resume.
