-Add Kodi-specific patch
-
-Kodi 15.0 contains an updated version of libsquish:
-https://github.com/xbmc/xbmc/tree/master/tools/depends/native/libsquish-native
-
-The OpenElec project provides a separate tarball including the Kodi-
-specific patches:
-http://sources.openelec.tv/devel/libsquish-1.10-openelec.tar.gz
-
-This patch contains the relevant diff between upstream libsquish 1.13
-and the OpenElec tarball.
