[media] drxk: Fix a bug at some switches that broke DVB-T
The error propagation changeset c23bf4402 broke the DVB-T
code.
The legacy way for propagate errors was:
do {
status = foo_func()
if (status < 0)
break;
} while (0);
return status;
However, on a few places, it was doing:
do {
switch(foo) {
case bar:
status = foo_func()
if (status < 0)
break;
break;
}
switch(foo2) {
case bar:
status = foo_func()
if (status < 0)
break;
break;
}
...
} while (0);
return (status)
The inner error break were not working, as it were breaking only
the switch, instead of the do. The solution used were to do a
s/break/goto error/ at the inner breaks, but preserving the last
break. Onfortunately, on a few switches, the replacement were
applied also to the final break for the case statements.
Fix the broken logic, by reverting them to break, where pertinent,
in order to fix DVB-T support.

[media] drxk: Fix a bug at some switches that broke DVB-T
The error propagation changeset c23bf4402 broke the DVB-T
code.
The legacy way for propagate errors was:
do {
status = foo_func()
if (status < 0)
break;
} while (0);
return status;
However, on a few places, it was doing:
do {
switch(foo) {
case bar:
status = foo_func()
if (status < 0)
break;
break;
}
switch(foo2) {
case bar:
status = foo_func()
if (status < 0)
break;
break;
}
...
} while (0);
return (status)
The inner error break were not working, as it were breaking only
the switch, instead of the do. The solution used were to do a
s/break/goto error/ at the inner breaks, but preserving the last
break. Onfortunately, on a few switches, the replacement were
applied also to the final break for the case statements.
Fix the broken logic, by reverting them to break, where pertinent,
in order to fix DVB-T support.

[media] drxk: Fix a bug at some switches that broke DVB-T
The error propagation changeset c23bf4402 broke the DVB-T
code.
The legacy way for propagate errors was:
do {
status = foo_func()
if (status < 0)
break;
} while (0);
return status;
However, on a few places, it was doing:
do {
switch(foo) {
case bar:
status = foo_func()
if (status < 0)
break;
break;
}
switch(foo2) {
case bar:
status = foo_func()
if (status < 0)
break;
break;
}
...
} while (0);
return (status)
The inner error break were not working, as it were breaking only
the switch, instead of the do. The solution used were to do a
s/break/goto error/ at the inner breaks, but preserving the last
break. Onfortunately, on a few switches, the replacement were
applied also to the final break for the case statements.
Fix the broken logic, by reverting them to break, where pertinent,
in order to fix DVB-T support.

[media] dvb-core, tda18271c2dd: define get_if_frequency() callback
Tuners in general convert a high frequency carrier into an Intermediate
Frequency (IF).
Digital tuners like tda18271, xc3028, etc. generally allow changing the IF
frequency, although they generally have recommented settings for the IF.
Analog tuners, have a fixed IF frequency, that depends on the physical
characteristics of some analog components.
For digital tuners, it makes sense to have ways to configure IF,
via the tuner's configuration structure, like what's done inside the
tda18271-fe maps.
The demods need to know what IF is used by the tuner, as it will need
to convert internally from IF into baseband. Currently, the bridge driver
needs to fill a per-demod configuration struct for it, or pass it via
a dvb_attach parameter.
The tda18271 datasheet recommends to use different IF's for different
delivery system types and for different bandwidths.
The DRX-K demod also needs to know the IF frequency in order to work,
just like all other demods. However, as it accepts different delivery
systems (DVB-C and DVB-T), the IF may change if the standard and/or
bandwidth is changed.
So, the usual procedure of passing it via a config struct doesn't work.
One might try to code it as two separate IF frequencies, or even as a
table in function of the delivery system and the bandwidth, but this
will be messy.
So, it is better and simpler to just add a new callback for it and
require the tuners that can be used with MFE frontends like drx-k
to implement a new callback to return the used IF.

[media] dvb-core, tda18271c2dd: define get_if_frequency() callback
Tuners in general convert a high frequency carrier into an Intermediate
Frequency (IF).
Digital tuners like tda18271, xc3028, etc. generally allow changing the IF
frequency, although they generally have recommented settings for the IF.
Analog tuners, have a fixed IF frequency, that depends on the physical
characteristics of some analog components.
For digital tuners, it makes sense to have ways to configure IF,
via the tuner's configuration structure, like what's done inside the
tda18271-fe maps.
The demods need to know what IF is used by the tuner, as it will need
to convert internally from IF into baseband. Currently, the bridge driver
needs to fill a per-demod configuration struct for it, or pass it via
a dvb_attach parameter.
The tda18271 datasheet recommends to use different IF's for different
delivery system types and for different bandwidths.
The DRX-K demod also needs to know the IF frequency in order to work,
just like all other demods. However, as it accepts different delivery
systems (DVB-C and DVB-T), the IF may change if the standard and/or
bandwidth is changed.
So, the usual procedure of passing it via a config struct doesn't work.
One might try to code it as two separate IF frequencies, or even as a
table in function of the delivery system and the bandwidth, but this
will be messy.
So, it is better and simpler to just add a new callback for it and
require the tuners that can be used with MFE frontends like drx-k
to implement a new callback to return the used IF.
