[MPlayer-dev-eng] [PATCH] v4l1 bugfix for hang on close

[Krister Lagerstrom]

The CVS update on oct 19 for libmpdemux/tvi_v4l.c broke TV viewing. It
now hangs on close. The included patch is a very simple fix for the
problem.

The source contains a mix of tabs and spaces, so my patch has only
spaces for indentation.

The patch was made using:

  "cvs diff -u libmpdemux/ > patch_v4l1_fix_hang_on_close"

using a 10 second old cvs update.
