3.16.72-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dragos Bogdan dragos.bogdan@analog.com
commit fccfb9ce70ed4ea7a145f77b86de62e38178517f upstream.
The desired channel has to be selected in order to correctly fill the buffer with the corresponding data. The `ad_sd_write_reg()` already does this, but for the `ad_sd_read_reg_raw()` this was omitted.
