From 8cf6874e84ba64488975a07fda267486a77ac5a3 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 5 Jun 2015 05:30:02 -0300 Subject: [PATCH] [media] v4l2-dv-timings: support interlaced in v4l2_print_dv_timings The v4l2_print_dv_timings() didn't log the interlaced format correctly. The timings for the bottom field weren't logged and the fields per second value was half of what it should have been.
