From abd23295648a9e3ae72a806e70a510d3dcd8b374 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Sat, 15 Sep 2012 07:51:47 -0300 Subject: [media] v4l: Helper function for obtaining timestamps v4l2_get_timestamp() produces a monotonic timestamp but unlike ktime_get_ts(), it uses struct timeval instead of struct timespec, saving the drivers the conversion job when getting timestamps for v4l2_buffer's timestamp field.
