Subject: [PATCH] Convert Wideview WT220 DVB USB driver to rc-core
(I don't know if this sort of patch is welcome, but if it is I have a
couple of other USB DVB sticks I will convert over as well. My main
motivation was to be able to easily use a better remote than the mini
one that comes with these devices.)
This patch converts the dtt200u DVB USB driver over to the rc-core
infrastructure for its handling of IR remotes. This device can receive
generic NEC / NEC Extended signals and the switch to the newer core
enables the easy use of tools such as ir-keytable to modify the active
key map.
