From: Lars-Peter Clausen Date: Fri, 4 Oct 2013 11:07:00 +0000 (+0100) Subject: iio:buffer: Ignore noop requests for iio_update_buffers() X-Git-Tag: omap-for-v3.13/fixes-for-merge-window-take2~62^2~196^2~45 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3909fab5a8afdf8f0c9191e3a2660230ef0ef724;p=pandora-kernel.git iio:buffer: Ignore noop requests for iio_update_buffers() Since the kernel now disables all buffers when a device is unregistered it might happen that a in-kernel consumer tries to disable that buffer again. So ignore requests where the buffer already is in the desired state. Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron --- Reading git-diff-tree failed
