From 90354d0038e9e3d82d5fee5442d48f7cafb96a0c Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 15 Apr 2012 17:41:22 +0100 Subject: [PATCH] staging:iio:light Add IIO_CHAN_INFO_RAW/PROCESSED entries to all drivers. Precursor to making value read / write attribute optional. Note that minimal change route taken here. The read_raw callbacks in both drivers could do fewer checks to identify the channel than they now do.
