From 4e8ec0a46f48c86b215a5b76f621927aa40a2440 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 10 Mar 2014 10:58:24 -0300 Subject: [PATCH] [media] mem2mem_testdev: pick default format with try_fmt This resolves an issue raised by v4l2-compliance: if the given format does not exist, then pick a default format. While there is an exception regarding this for TV capture drivers, this m2m driver should do the right thing.
