From 5ba0e2c3ad4c049b19f6cad7ec62e59424a55183 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 17 Sep 2015 18:19:37 -0300 Subject: [media] use v4l2_get_timestamp where possible This is a preparation for a change to the type of v4l2 timestamps. v4l2_get_timestamp() is a helper function that reads the monotonic time and stores it into a 'struct timeval'. Multiple drivers implement the same thing themselves for historic reasons. Changing them all to use v4l2_get_timestamp() is more consistent and reduces the amount of code duplication, and most importantly simplifies the following changes.
