From 637bc2079678e08476d884f02a5d5d3208b5c018 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 29 Aug 2014 03:46:05 -0300 Subject: [PATCH] [media] cx88: remove fmt from the buffer struct This is a duplicate of dev->fmt and can be removed. As a consequence a lot of tests that check if the format has changed midstream can be removed as well: the format cannot change midstream, so this is a bogus check.
