This patchset fixes problem with inv_mpu6050 driver,
when it fails after device is suspended by runtime pm during a probe.
To simplify runtime pm handling in the driver more devm-helpers are used.

Andrey Skvortsov (3):
iio: imu: inv_mpu6050: fix unbalanced regulator_disable calls, when
probe fails
iio: imu: inv_mpu6050: use devres-enabled version of pm_runtime_enable
iio: imu: inv_mpu6050: control vdd supply using devm-helpers

Changes in v3:
- make patch "fix unbalanced regulator_disable calls, when probe fails"
with Fixes to be the first patch of the patchset for easier backporting
- don't move pm_runtime_set_active, move devm_add_action_or_reset for
inv_mpu_core_disable_regulator_action instead
- update commit message in "fix unbalanced regulator_disable calls,
when probe fails" to fix Andy's comment
- remove blank lines in "use devres-enabled version of pm_runtime_enable"
- no dead code in inv_mpu_core_disable_regulator_action anymore since
st variable is used to get 'struct device' now

Changes in v2:
- minimize call trace in commit message
- use runtime pm framework to track vddio regulator state
- include specific driver name in patch subject
- add more patches to use device managed functions
