V4L/DVB (7384): tda18271: store FM_RFn setting in struct tda18271_std_map_item
All standard related configuration is stored within struct tda18271_std_map_item. Pass a pointer to this structure rather than its individual members. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
