Instead of using a table for reg bitmask, use a macro. This should save
some data segment space.

commit 9ef449c6b3 ("[media] rc: Postpone ISR
registration") fixed an early ISR registration on several drivers. It did
however also introduced a bug by moving the invocation of pnp_port_start()
to the end of the probe function.
This patch fixes this issue by moving the invocation of pnp_port_start() to
an earlier stage in the probe function.

Implement API support to return AFC frequency shift, as this device
supports it. The only other driver that implements it is tda9887,
and the frequency there is reported in Hz. So, use Hz also for this
tuner.

There are several bugs at the signal strength algorithm:
- It is using logical OR, instead of bit OR;
- It doesn't wait up to 18 ms as it should;
- the strength range is not ok.
Rework on it, in order to make it work.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
If g_tuner is called and the tuner is able to return the signal strength
via has_signal(), call the tunner callback to retrieve such data for all
tuner types, not only for radio ones.

Change the firmware logic to use request_firmware_nowait(), and
to preserve the loaded firmwares in memory, to reduce the risk
of troubles with buggy userspace apps.
With this change, while the firmware is being loaded, the driver
will return -EAGAIN to any calls. If, for some reason, firmware
failed to be loaded from userspace, it will return -ENODEV.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
If firmware is not loaded for some reason, or if it is not ready
yet, it makes no sense to honour to any DVB callbacks.
So, return -EAGAIN, as the error condition may be temporary.
If the device doesn't initialize, either because it requires a
firmware or because there's an error during init_drxk, returns
-ENODEV, to indicate such error, on all DVB callbacks.

As it will be using the unlocked version of i2c_transfer during
firmware loads, make sure that the priv state routine will be
used on all I2C calls, in preparation for the next patch that
will implement an exclusive lock mode to be used during firmware
load, at drxk_init.

The firmware blob may not be available when the driver probes.
Instead of blocking the whole kernel use request_firmware_nowait() and
continue without firmware.
This shouldn't be that bad on drx-k devices, as they all seem to have an
internal firmware. So, only the firmware update will take a little longer
to happen.

Some drivers (in particular for TV cards) need exclusive access to
their I2C buses for specific operations. Export an unlocked flavor
of i2c_transfer to give them full control.
The unlocked flavor has the following limitations:
* Obviously, caller must hold the i2c adapter lock.
* No debug messages are logged. We don't want to log messages while
holding a rt_mutex.
* No check is done on the existence of adap->algo->master_xfer. It
is thus the caller's responsibility to ensure that the function is
OK to call.

The windows driver used different values for the GPIOs and analog
decoder configuration. The values from the windows driver are now
used.
It also seems that the windows driver has LNA always disabled.
Thus we are doing the same (using the same flags as on windows).
