The module needs an external firmware file. The module has been tested on a Pinnacle 330e, but with modules that are currently not part of the linux-dvb tree. So consider this highly experimental, don't use this code unless you are an experienced kernel developer. create mode 100644 drivers/media/dvb/frontends/drx397xD.c create mode 100644 drivers/media/dvb/frontends/drx397xD.h create mode 100644 drivers/media/dvb/frontends/drx397xD_fw.h Signed-off-by: Henk Vergonet <henk.vergonet@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
