i2c bus is already needed when the frontend is probed, so init it already in it930x_frontend_attach That prevents errors like si2168: probe of 6-0067 failed with error -5 Signed-off-by: Andreas Kemnade <andreas@kemnade.info> --- drivers/media/usb/dvb-usb-v2/af9035.c | 43 ++++++++++++++++++++++++++++++++++- 1 file changed, 42 insertions(+), 1 deletion(-)
