From 314527acbbb3f33f72c2ef19d8cfabcada9912a5 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 15 Mar 2013 06:10:40 -0300 Subject: [media] v4l2: pass std by value to the write-only s_std ioctl This ioctl is defined as IOW, so pass the argument by value instead of by reference. I could have chosen to add const instead, but this is 1) easier to handle in drivers and 2) consistent with the s_std subdev operation.
