From: Jonathan Cameron Date: Tue, 30 Aug 2011 11:41:06 +0000 (+0100) Subject: staging:iio: remove broken support for multiple event interfaces. X-Git-Tag: next-20111004~7^2~456 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5aa9618896e0ba49;p=karo-tx-linux.git staging:iio: remove broken support for multiple event interfaces. We don't have a use case for these. Two drivers appeared to use them but both report all events on the first. V2: Remove now irrelevant comment.
