4.19-stable review patch. If anyone has any objections, please let me know.

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().
[...]
This (and other) backports missed a couple of affected exports:
- sp8870_attach in drivers/media/dvb-frontends/sp8870.c (renamed to drivers/staging/media/av7110/sp8870.c upstream)
- xc2028_attach in drivers/media/tuners/tuner-xc2028.c (renamed to drivers/media/tuners/xc2028.c upstream)
Thanks for catching this, fixed up now for 4.14.y and 4.19.y.
