[PATCH] iio: imu: inv_icm42600: enable temp polling when buffer is on
Posted by Jean-Baptiste Maneyrol via B4 Relay 1 month, 3 weeks ago
From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@tdk.com>

Delete iio_device_claim_direct_mode() when reading temperature.
It enables polling of temperature data while buffer is on and it
doesn't have any impact on the other sensors.

Applied to the togreg branch of iio.git. Initially pushed out as testing
to let 0-day take a look at it.

Thanks,
