From 3ae17c66ed666c5a5c627f28c9e20b2ab8fafe28 Mon Sep 17 00:00:00 2001 From: Jose Abreu Date: Tue, 21 Mar 2017 07:49:18 -0400 Subject: [PATCH] media: cobalt: Use v4l2_calc_timeperframe helper Currently, cobalt driver always returns 60fps in g_parm. This patch uses the new v4l2_calc_timeperframe helper to calculate the time per frame value.
