From: Jonathan Cameron Date: Wed, 18 May 2011 13:41:58 +0000 (+0100) Subject: staging:iio:accel:adis16240 move to chan_spec based setup. X-Git-Tag: firefly_0821_release~7613^2~1326^2~44 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=cd69f57dee75cb27337bf5438359aae86503873f;p=firefly-linux-kernel-4.4.55.git staging:iio:accel:adis16240 move to chan_spec based setup. For clean drivers its easier to convert to chan_spec based registration than to work around the scan_el attributes going away. Some minor cleanups done whilst here. Untested. V2: IIO_CHAN macro use updated.
