Subject: [PATCH 3.17 194/319] staging:iio:ade7758: Fix check if channels are enabled in prenable

3.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lars-Peter Clausen <lars@...afoo.de>

commit 79fa64eb2ee8ccb4bcad7f54caa2699730b10b22 upstream.

We should check if a channel is enabled, not if no channels are enabled.

Fixes: 550268ca1111 ("staging:iio: scrap scan_count and ensure all drivers use active_scan_mask")
