[PATCH v4 2/3] iio: imu: inv_mpu6050: use devres-enabled version of pm_runtime_enable()

[Andrey Skvortsov]

Usage of devm_pm_runtime_enable() allows to remove driver-specific
action, that does the same as default action.

Signed-off-by: Andrey Skvortsov <andrej.skvortzov@xxxxxxxxx>

Changes in v4:
 - update commit message to address Andy's comment
   about functions, callbacks and runtime PM names

Changes in v3:
 - remove extra blank lines in "use devres-enabled version of pm_runtime_enable"
