[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 <tvboxspy@gmail.com> Cc: <stable@vger.kernel.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
