If anyone has any objections, please let me know. ------------------ From: Malcolm Priestley commit c9d57de6103e343f2d4e04ea8d9e417e10a24da7 upstream. When in FE_TUNE_MODE_ONESHOT the frontend must report the actual capabilities so user can take appropriate action. With frontends that can't do auto inversion this is done by dvb-core automatically so CAN_INVERSION_AUTO is valid. However, when in FE_TUNE_MODE_ONESHOT this is not true. So only set FE_CAN_INVERSION_AUTO in modes other than FE_TUNE_MODE_ONESHOT Signed-off-by: Malcolm Priestley Signed-off-by: Mauro Carvalho Chehab [bwh: Backported to 3.2: adjust filename] Signed-off-by: Ben Hutchings --- drivers/media/dvb/dvb-core/dvb_frontend.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) --- a/drivers/media/dvb/dvb-core/dvb_frontend.c +++ b/drivers/media/dvb/dvb-core/dvb_frontend.c @@ -1661,9 +1661,9 @@ static int dvb_frontend_ioctl_legacy(str memcpy(info, &fe->ops.info, sizeof(struct dvb_frontend_info)); dvb_frontend_get_frequency_limits(fe, &info->frequency_min, &info->frequency_max); - /* Force the CAN_INVERSION_AUTO bit on.
