media: dvb: symbol fixup for dvb_attach() 



commit 86495af1171e1feec79faa9b64c05c89f46e41d1 upstream.

In commit 9011e49d54dc ("modules: only allow symbol_get of
EXPORT_SYMBOL_GPL modules") the use of symbol_get is properly restricted
to GPL-only marked symbols.  This interacts oddly with the DVB logic
which only uses dvb_attach() to load the dvb driver which then uses
symbol_get().

Fix this up by properly marking all of the dvb_attach attach symbols as
EXPORT_SYMBOL_GPL().
