From a13e831fcaa7e8af0387aef629d1835cf39c59f0 Mon Sep 17 00:00:00 2001 From: Eva Rachel Retuya Date: Wed, 5 Oct 2016 11:06:21 +0800 Subject: staging: iio: ad7192: implement IIO_CHAN_INFO_SAMP_FREQ This driver predates the availability of IIO_CHAN_INFO_SAMP_FREQ attribute wherein usage has some advantages like it can be accessed by in-kernel consumers as well as reduces the code size. Therefore, use IIO_CHAN_INFO_SAMP_FREQ to implement the sampling_frequency attribute instead of using IIO_DEV_ATTR_SAMP_FREQ() macro. Move code from the functions associated with IIO_DEV_ATTR_SAMP_FREQ() into respective read and write hooks with the mask set to IIO_CHAN_INFO_SAMP_FREQ.
