From c4b72ee8acce3d1e2a2fe7398aac9567deebf837 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 13 Dec 2017 18:44:42 -0500 Subject: [PATCH] media: pvrusb2: correctly return V4L2_PIX_FMT_MPEG in enum_fmt The pvrusb2 code appears to have a some old workaround code for xawtv that causes a WARN() due to an unrecognized pixelformat 0 in v4l2_ioctl.c. Since all other MPEG drivers fill this in correctly, it is a safe assumption that this particular problem no longer exists. While I'm at it, clean up the code a bit.
