V4L/DVB (6893): tuner-xc2028: fix xc2028_attach function
xc2028_attach was returning an integer when disabled from the build, where it should instead be returning NULL. Declare xc2028_attach as type dvb_frontend * instead of void *. The prototype declaration must be marked as extern in the header. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
