Subject: [PATCH 3.19.y-ckt 008/210] [media] media: dvb-core: Don't force CAN_INVERSION_AUTO in oneshot mode
3.19.8-ckt14 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Malcolm Priestley <tvboxspy@...il.com>
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
