This was introduced on commit c2a6b54a9:
"em28xx: fix: don't do image interlacing on webcams"
The proposed patch by Ezequiel is wrong. The right fix here is to just
don't bother here if either the image is progressive or not.

Currently there are two different implementations (in the firmware) for
the QAM demodulator command: one takes 4 and the other takes 2
parameters. The driver shows an error in dmesg When using the
4-parameter command with firmware that implements the 2-parameter
command. Unfortunately this happens every time when chaning the
frequency (on DVB-C).
This patch simply makes configurable, how many command parameters will
be used. All existing drxk_config instances using the "drxk_a3.mc" were
updated because this firmware is the only loadable firmware where the
QAM demodulator command takes 4 parameters. Some firmwares in the ROM
might also use it. The drxk instances in the em28xx-dvb driver were also
updated to silence the warnings.
If no qam_demod_parameter_count is given in the drxk_config struct, then
the correct number of parameters will be auto-detected.

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).
I (only) tested with DVB-T and it worked quite well.

Enable the LNA amplifier also for DVB-T (like for DVB-T2 and DVB-C);
this greatly improves reception of weak signals without affecting the reception
of the strong ones.
Experimental data (collected with the mipsel STB) on the weakest frequencies
available in my area:
LNA OFF:
MUX level BER picture
RAI mux 4 72% 32000 corrupted
TIMB 2 75% 14 OK
TVA Vicenza 68% 32000 corrupted
RAI mux 2 78% 14 OK
LNA ON:
MUX level BER picture
RAI mux 4 73% 1500 OK
TIMB 2 76% 0 OK
TVA Vicenza 69% 0 OK
RAI mux 2 79% 0 OK
Moreover, with LNA enabled, the PCTV 290e was able to pick up 2 new frequencies
matching the integrated tuner of my Panasonic G20 TV, which is really good.

This used to be the default if the lock pointer was set, but now that lock is by
default only used for ioctl serialization. Those drivers that already used
core locking have this flag set explicitly, except for some drivers where
it was obvious that there was no need to serialize any file operations other
than ioctl.
The drivers that didn't need this flag were:
drivers/media/radio/dsbr100.c
drivers/media/radio/radio-isa.c
drivers/media/radio/radio-keene.c
drivers/media/radio/radio-miropcm20.c
drivers/media/radio/radio-mr800.c
drivers/media/radio/radio-tea5764.c
drivers/media/radio/radio-timb.c
drivers/media/video/vivi.c
sound/i2c/other/tea575x-tuner.c
The other drivers that use core locking and where it was not immediately
obvious that this flag wasn't needed were changed so that the flag is set
together with a comment that that driver needs work to avoid having to
set that flag. This will often involve taking the core lock in the fops
themselves.
Eventually this flag should go and it should not be used in new drivers.
There are a few reasons why we want to avoid core locking of non-ioctl
fops: in the case of mmap this can lead to a deadlock in rare situations
since when mmap is called the mmap_sem is held and it is possible for
other parts of the code to take that lock as well (copy_from_user()/copy_to_user()
perform a down_read(&mm->mmap_sem) when a page fault occurs).
It is very unlikely that that happens since the core lock serializes all
fops, but the kernel warns about it if lock validation is turned on.
For poll it is also undesirable to take the core lock as that can introduce
increased latency. The same is true for read/write.
While it was possible to make flags or something to turn on/off taking the
core lock for each file operation, in practice it is much simpler to just
not take it at all except for ioctl and leave it to the driver to take the
lock. There are only a handful fops compared to the zillion ioctls we have.
I also wanted to make it obvious which drivers still take the lock for all
fops, so that's why I chose to have drivers set it explicitly.

It is mostly copy/paste of the 520e code with setting GPIO7 removed
(no LED light).
I've worked on just released vanilla linux-3.3.0 kernel, so there may
be 1/2 lines offset to the internal working source, but most of the
code should apply cleanly.
I was able to get the DVB-C working (tuned and watched TV). Haven't
tested DVB-T (no signal atm).
Special thanks to everybody who worked on the code and to Antti
Palosaari and Devin Heitmueller who provided essential support on irc.

On MIPS/ARM set-top-boxes, as well as old x86 PCs, memory allocation failures
in the em28xx driver are common, due to memory fragmentation over time, that
makes impossible to allocate large chunks of coherent memory.
A typical system with 256/512 MB of RAM fails after just 1 day of uptime (see
the old thread for detailed reports and crashlogs).
In fact, the em28xx driver allocates memory for USB isoc transfers at runtime,
as opposite to the dvb-usb drivers that allocates the USB buffers when the
device is initialized, and frees them when the device is disconnected.
Moreover, in digital mode the USB isoc transfer buffers are freed, allocated
and cleared every time the user selects a new channel, wasting time and
resources.
This patch solves both problems by allocating DVB isoc transfer buffers in
em28xx_usb_probe(), and freeing them in em28xx_usb_disconnect().
In fact, the buffers size and number depend only on the max USB packet size
that is parsed from the USB descriptors in em28xx_usb_probe(), so it can
never change for a given device.
This approach makes no sense in analog mode (as the buffer size depends on
the alternate mode selected at runtime), the patch creates two separate sets
of buffers for digital and analog modes.
For digital-only devices, USB buffers are created when the device is probed
and freed when the device is disconnected.
For analog-only devices, nothing changes: isoc buffers are created at runtime.
For hybrid devices, two sets of buffers are maintained: the digital-mode
buffers are created when the device is probed, and freed when the device is
disconnected; analog-mode buffers are created/destroyed at runtime as before.
So, in analog mode, digital and analog buffers coexists at the same time: this
can be justified by the fact that digital mode is by far more commonly used
nowadays, so it makes sense to optimize the driver for this use case scenario.
The patch has been tested in the last few days on a x86 PC and a MIPS
set-top-box, with the PCTV 290e (digital only) and the Terratec Hybrid XS
(hybrid device). With the latter, I switched several times between analog and
digital mode (Kaffeine/TvTime) with no issue at all.
I unplugged/plugged the devices several times with no problem.
Also, after over 3 days of normal usage in the MPIS set-top-box, the PCTV 290e
was still up and running.
