From 183bec80ce80b3f71dadb601e7e2fc9f712b1d52 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Tue, 16 Sep 2014 16:19:37 -0300 Subject: [PATCH] [media] smiapp: Split calculating PLL with sensor's limits from updating it The first one is handy for just trying out a PLL configuration without a need to apply it.
