[libdvdnav-devel] Initialize dvd_reader_t struct in DVDOpenImageFile

[Richard Hulme]

libdvdread | branch: master | Richard Hulme <peper03 at yahoo.com> | Sun Jan 26 17:13:03 2014 +0100| [7c743650d038ee280f990cfb7d5f867842ee7369] | committer: Jean-Baptiste Kempf

Initialize dvd_reader_t struct in DVDOpenImageFile

This ensures that the dvd_reader_t struct is initialized (e.g. the css_state
field is currently undefined if 'have_css' is false).

The patch is part of a bigger MythTV-specific change by Chris Pinkham:
