media: dvb-frontends/stv0367: improve QAM fe_status
While cab_state->state gives a quite accurate indication of the demod
signal status, it might be incorrect if cab_algo() wasn't able to
determine the exact status, with cab_algo() being the only place where
this status was updated from, and it is only called upon tuning to new
parameters passed to set_frontend(). Thus, the status will be wrong
until the demod is retuned. With the cab_signal_type parsing in
read_status(), this results in unusual fe_states like FE_HAS_SIGNAL |
FE_HAS_CARRIER | FE_HAS_LOCK, which, while userspace applications check
for FE_HAS_LOCK and work fine, leads to missing CNR or UCB stats.
Fix this by re-reading CAB_FSM_STATUS and updating cab_state->state() in
read_status(). While at it, refactor the fsm/qamfeclock and the
fsm->signaltype parsing into separate functions to make things cleaner
and deduplicate code. Also, assume full QAM FEC lock equals full
FE_STATUS.

read_status(), this results in unusual fe_states like FE_HAS_SIGNAL |
FE_HAS_CARRIER | FE_HAS_LOCK, which, while userspace applications check
for FE_HAS_LOCK and work fine, leads to missing CNR or UCB stats.
Fix this by re-reading CAB_FSM_STATUS and updating cab_state->state() in
read_status(). While at it, refactor the fsm/qamfeclock and the
fsm->signaltype parsing into separate functions to make things cleaner
and deduplicate code. Also, assume full QAM FEC lock equals full

media: dvb-frontends/stv0367: improve QAM fe_status
While cab_state->state gives a quite accurate indication of the demod
signal status, it might be incorrect if cab_algo() wasn't able to
determine the exact status, with cab_algo() being the only place where
this status was updated from, and it is only called upon tuning to new
parameters passed to set_frontend(). Thus, the status will be wrong
until the demod is retuned. With the cab_signal_type parsing in
read_status(), this results in unusual fe_states like FE_HAS_SIGNAL |
FE_HAS_CARRIER | FE_HAS_LOCK, which, while userspace applications check
for FE_HAS_LOCK and work fine, leads to missing CNR or UCB stats.
Fix this by re-reading CAB_FSM_STATUS and updating cab_state->state() in
read_status(). While at it, refactor the fsm/qamfeclock and the
fsm->signaltype parsing into separate functions to make things cleaner
and deduplicate code. Also, assume full QAM FEC lock equals full
FE_STATUS.

media: dvb-frontends/stv0367: improve QAM fe_status
While cab_state->state gives a quite accurate indication of the demod
signal status, it might be incorrect if cab_algo() wasn't able to
determine the exact status, with cab_algo() being the only place where
this status was updated from, and it is only called upon tuning to new
parameters passed to set_frontend(). Thus, the status will be wrong
until the demod is retuned. With the cab_signal_type parsing in
read_status(), this results in unusual fe_states like FE_HAS_SIGNAL |
FE_HAS_CARRIER | FE_HAS_LOCK, which, while userspace applications check
for FE_HAS_LOCK and work fine, leads to missing CNR or UCB stats.
Fix this by re-reading CAB_FSM_STATUS and updating cab_state->state() in
read_status(). While at it, refactor the fsm/qamfeclock and the
fsm->signaltype parsing into separate functions to make things cleaner
and deduplicate code. Also, assume full QAM FEC lock equals full
FE_STATUS.
