Date: Sun, 28 Mar 2021 18:46:26 -0300 From: Lucas Stankus <lucas.p.stankus@...il.com> To: lars@...afoo.de, Michael.Hennerich@...log.com, jic23@...nel.org Cc: linux-iio@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 2/3] iio: adc: ad7923: use device-managed function for triggered buffer 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.
