Hello,

This patch introduces a system suspend-resume regressing, I'm seeing the
following on entering into suspend:

 vdd_gen1v8: Underflow of regulator enable count
 inv-mpu6050-i2c 1-0068: Failed to disable vddio regulator: -22

Apparently RPM disables the regulator and then it's erroneously disabled
second time on suspend. Please fix it, thanks in advance.
