[2/3] iio: adc: ad7923: use device-managed function for triggered buffer

Series iio: adc: ad7923: convert driver resources routines to device-managed counterparts | expand

Commit Message

Lucas Stankus March 28, 2021, 9:46 p.m. UTC 
Converts the iio_triggered_buffer_setup() call to its device-managed
counterpart.
With this, the error handling routine in the ad7923_probe() function
becomes unnecessary as well as the iio_triggered_buffer_cleanup() call.
