Subject: iio: ad799x: Fix buffered capture for ad7991/ad7995/ad7999

From: Lars-Peter Clausen <[email protected]>

commit 7d3cc21dab5313a02f2f3ca8164529b828a030d1 upstream.

The data buffer for captured mode for the ad799x driver is allocated in the update_scan_mode() callback. This callback is not set in the iio_info struct for the ad7791/ad7995/ad7999, which means that the data buffer is not allocated when a captured transfer is started. As a result the driver crashes when the first sample is received. To fix this properly set the update_scan_mode() callback.
