Various frontend driver have parameter checks in their set_frontend
functions and return an error if the parameters are not supported,
tda10021 and cx24116 to name two.
The tuning ioctls FE_SET_FRONTEND/FE_SET_PROPERTY only change values
in the property cache and return before set_frontend is called. If a
set_frontend call in software zigzag algorithm fails and the card was
previously locked it will report a lock and the new parameters but is
still tuned to the old transport. This is not detectable from
userspace.
This change checks the return values of fe->ops.set_frontend and
changes the state to the added FESTATE_ERROR for software zigzag.
No lock will be reported to userspace if the State is FESTATE_ERROR.

The input subsystem checks if get_keycode works for a scan code. Due to that,
we need to return a valid value when there's some space at the table that
can be used by a scancode.

Implements handler for EVIOCGKEYCODE/EVIOCSKEYCODE via adding two new callbacks
to the input device.
Since on dvb-usb a scan code has 16 bits, to fulfill rc5 standard codes, the default
getkeycode/setkeycode input methods would require the driver to spend up to 64 Kb of
a sparse table. Instead, add two new callbacks to the event device.
With this, it is now possible to replace the keycode tables. There are, however, a few
implementation details at the current patch:
1) It will replace the existing device keytable, instead of creating an instance
of the data. This works. However, if two devices pointing to the same table
were connected, changing the IR table of one will also change the IR table for
the other (the solution for this one is simple: just kmalloc some memory);
2) In order to change the scan code, you need first to change the key to
KEY_RESERVED or KEY_UNKNOWN to free some space at the table (solution: allocate
some additional space for newer scan codes or allow dynamic table grow);
3) The table size cannot be extended. It would be easy to allow the table to
grow dynamically: just calling kmalloc(size+1); kfree(old). Yet, maybe we can
just create a bigger table with a fixed size, like for example a table with 128
entries. This should be enough even for a very big IR.
The current issues should be addressed on a later patch.

In order to be closer to V4L IR implementation, it is needed to replace
u8 custom, data
to:
u16 scan
This allows using non-rc5 mappings, like the 8 bit keycodes used on older
protocols. It will also allow future implementations of rc6 keystrokes
when needed.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
Currently, V4L uses a scancode table whose index is the scancode and
the value is the keycode. While this works, it has some drawbacks:
1) It requires that the scancode to be at the range 00-7f;
2) keycodes should be masked on 7 bits in order for it to work;
3) due to the 7 bits approach, sometimes it is not possible to replace
the default keyboard to another one with a different encoding rule;
4) it is different than what is done with dvb-usb approach;
5) it requires a typedef for it to work. This is not a recommended
Linux CodingStyle.
This patch is part of a larger series of IR changes. It basically
replaces the IR_KEYTAB_TYPE tables by a structured table:
struct ir_scancode {
u16 scancode;
u32 keycode;
};
This is very close to what dvb does. So, a further integration with DVB
code will be easy.
While we've changed the tables, for now, the IR keycode handling is still
based on the old approach.
The only notable effect is the redution of about 35% of the ir-common
module size:
text data bss dec hex filename
6721 29208 4 35933 8c5d old/ir-common.ko
5756 18040 4 23800 5cf8 new/ir-common.ko
In thesis, we could be using above u8 for scancode, reducing even more the size
of the module, but defining it as u16 is more convenient, since, on dvb, each
scancode has up to 16 bits, and we currently have a few troubles with rc5, as their
scancodes are defined with more than 8 bits.
This patch itself shouldn't be doing any functional changes.

The AVC protocol uses the same command for tuning and PID filtering and
since dvb-core uses a software zigzagging to do automatic retuning this
could cause all PID filters to be cleared. PID filter information is
now included in all DSD commands to the card.
Background:
There is a problem in the firedtv driver that causes recordings to stop
if the SW zigzag algorithm in dvb-core kicks in with a retune after the
application has set up the PID filters. Since tuning and setting PID
filters uses the same AVC command (DSD) and only the replace subfunction
is supported by the card, it is not possible to do a retune without
setting the PID filters. This means that the PID filtering has to be
sent in each tune.
This problem applies to C and T cards since S and S2 cards tune using a
vendor specific command. The patch corrects the problem by sending the
PID list in each tune. I have tested it on my T card with a good
result.
How to trigger problem: Zap to a channel and output AV to a file, e.g.
"tzap -c channels.conf SVT1 -r -o SVT1.ts". After a short while, pull
the antenna cable from the card. The lock on the channel will disappear
and the TS file will stop increasing in size. Wait a couple of seconds.
Replug the cable again. You will get a lock on the channel again, but
the TS file will never increase in size agains sinze no PIDS are
filtered.
Tested with kaffeine with DVB-T and DVB-C: Fixes retuning after antenna
was plugged out and back in with DVB-T. Does not fix this with DVB-C,
but also doesn't regress on DVB-C.

Attached is a patch which fixes tuning to low frequency channels with
stb0899+tda8261 cards like the KNC TV-Station DVB-S2.
The cause of the issue was a broken if construct, which should have been
an if/else if, so that the setting for the lowest matching frequency is
applied.
Without this patch for example tuning to "arte" on Astra 19.2, 10744MHz
SR22000 failed most times and when it failed the communication between
driver and tda8261 was completely broken.

Replace printing to magically sized temporary buffer with use
of KERN_CONT for continual printing of eeprom registers dump.
Since deb_info is defined as dprintk, which is conditionally defined
to printk without additional parameters, meaning that deb_info is equivalent
to direct printk (without adding KERN_ facility), we can use KERN_DEBUG and
KERN_CONT in there, eliminating the need for sprintf into temporary buffer
with not easily readable/magical size.
Though it's strange, that deb_info definition uses printk without KERN_
