From ce7ea56c270451820cfcc0c96aa6a73516b061ee Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sat, 12 May 2012 15:39:35 +0200 Subject: [PATCH] staging:iio:adis16204_read_ring_data: Pass IIO device directly When calling adis16204_read_ring_data we pass the device struct of embedded in the IIO device only to look up the IIO device from the device struct again right away. This patch changes the code to pass the IIO device directly.
