From c9d57de6103e343f2d4e04ea8d9e417e10a24da7 Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Mon, 31 Aug 2015 06:13:45 -0300 Subject: [media] media: dvb-core: Don't force CAN_INVERSION_AUTO in oneshot mode 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 Cc: Signed-off-by: Mauro Carvalho Chehab diff --git a/drivers/media/dvb-core/dvb_frontend.c b/drivers/media/dvb-core/dvb_frontend.c index 0b52cfc..fe6fa80 100644 --- a/drivers/media/dvb-core/dvb_frontend.c +++ b/drivers/media/dvb-core/dvb_frontend.c @@ -2314,9 +2314,9 @@ static int dvb_frontend_ioctl_legacy(struct file *file, dev_dbg(fe->dvb->device, "%s: current delivery system on cache: %d, V3 type: %d\n", __func__, c->delivery_system, fe->ops.info.type); - /* Force the CAN_INVERSION_AUTO bit on.
