[PATCH v2] iio: gyro: adis16260: replace mlock with ADIS lib's state_lock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This change uses the ADIS library's state_lock to protect the state of the
`max_speed_hz` change that is done during the set of the sampling
frequency.

Changelog v1 -> v2:
* use ADIS library's state_lock instead indio_dev's mlock ; vs just
  removing it (as V1 did)
