Julia Lawall 3227c860b6 V4L/DVB (12477): Use dst_type field instead of type_flags

Jan Nikitenko 43f8de7ac6 V4L/DVB (12342): af9015: avoid magically sized temporary buffer in eeprom_dump
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_
facility and callers don't use it either.

Trent Piepho 7a6fbd8337 V4L/DVB (12294): b2c2: Use dvb-pll for Cablestar2
The dvb-pll code should do the same thing that
alps_tdee4_stv0297_tuner_set_params() was doing.  Except the dvb-pll code
will check for tuner presence when attaching, while the old code didn't.

This tuner appears to not be behind the stv0297's I2C gate but is instead
on a different I2C adapter provided by the flexcop chip.  The old code
would turn the I2C gate off each time the tuner was used.  I've changed it
to turn the gate off when the tuner is attached and then disable the gate
control function.  This should result in the gate staying off, which should
be even better.

while the dvb-pll driver is designed for 15 bit divisors.  It's not a
problem as 15 bits is enough for the tuner's entire range.  But if a larger
range was wanted, it could be done by adding additional bands with the
extra divisor bits appearing as band switch bits.

Andreas Oberritter 1cb662a314 V4L/DVB (12275): Add two new ioctls: DMX_ADD_PID and DMX_REMOVE_PID
DMX_ADD_PID allows to add multiple PIDs to a transport stream filter
previously set up with DMX_SET_PES_FILTER and output=DMX_OUT_TSDEMUX_TAP.

DMX_REMOVE_PID is used to drop a PID from a filter.

These ioctls are to be used by readers of /dev/dvb/adapterX/demuxY. They
may be called at any time, i.e. before or after the first filter on the
shared file descriptor was started.

They make it possible to record multiple services without the need to de-
or re-multiplex TS packets.

To accomplish this, dmxdev_filter->feed.ts has been converted to a list
of struct dmxdev_feeds, each containing a PID value and a pointer to a
struct dmx_ts_feed.

Matthias Schwarzott 084e24acc9 V4L/DVB (12440): Use kzalloc for frontend states to have struct dvb_frontend properly
This patch changes most frontend drivers to allocate their state structure via
kzalloc and not kmalloc. This is done to properly initialize the
embedded "struct dvb_frontend frontend" field, that they all have.

The visible effect of this struct being uninitalized is, that the member "id"
that is used to set the name of kernel thread is totally random.

Some board drivers (for example cx88-dvb) set this "id" via
videobuf_dvb_alloc_frontend but most do not.

So I at least get random id values for saa7134, flexcop and ttpci based cards.
It looks like this in dmesg:
DVB: registering adapter 1 frontend -10551321 (ST STV0299 DVB-S)

The related kernel thread then also gets a strange name
like "kdvb-ad-1-fe--1".

Alexey Dobriyan 405f55712d headers: smp_lock.h redux
* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)

Patrick McHardy 6ed106549d net: use NETDEV_TX_OK instead of 0 in ndo_start_xmit() functions
This patch is the result of an automatic spatch transformation to convert
all ndo_start_xmit() return values of 0 to NETDEV_TX_OK.

Some occurences are missed by the automatic conversion, those will be
handled in a seperate patch.

Manu Abraham eebf8d86ac V4L/DVB (12131): BUGFIX: An incorrect Carrier Recovery Loop optimization table was being
loaded for a given chip version. This would cause the optimization in
tuning not to be applied and thus a failed expectation, in tuning speed
increment. The patch swaps the tables in use. It also fixes a possible
one in a million condition where state->dev_ver implies an older Cut
(Cut < 2.0, eventhough the driver doesn't attach to any Cut older than
2.0) or even negative (due to a bad I2C bus master driver) for the card
combination.

Changeset 1589a993f0 broke user visible
names of flexcop-pci devices, as it did reorder the enum of card types,
but did not adjust the array containing the card names.

Reorder the names, and uses [FC_AIR_DVBT] = "Air2PC/AirStar 2 DVB-T"
assignment style for more clarity.

It also adds the revision Number to the name for SkyStar rev. 2.3 and rev 2.6
as I think it is useful to see in log output.

have been applied:
1) core header - update statistics headers.
2) dvb adapter - omit the statistics request, add handling of
status indications.
3) core 'onresponse' - re-route messages addressed to other adapter
to the dvb adapter.

Devin Heitmueller a5beb7b323 V4L/DVB (11875): dvb_frontend: fix case where fepriv->exit not reset
The fact that we now explicitly set fepriv->exit = 1 when the thread is
shutting down exposed an edge case where it was not being reset back to zero
once the thread went away in some cases.  This resulted in failures in cases
where the frontend was closed, and then opened O_RDONLY, since in that case
the thread is not being restarted but it was checking the fepriv->exit flag.

Thanks to Thierry Lelegard, who and encountered and debugged a large portion
of the issue in the same twelve hours that I did (as well as testing my patch).

Devin Heitmueller 57594a586f V4L/DVB (11785): dvb_frontend: fix race condition resulting in dropped tuning commands
A race condition was detected in the case that putting the tuner to sleep takes
an unusually long period of time, combined with applications that quickly
close/open the dvb frontend.

The kaffeine channel scanner closes and reopens the dvb frontend between each
tuning attempt.  If it takes an unusually longer period of time to put the
tuner to sleep (for example, the Pinnacle 801e takes 660 ms), the dvb_frontend
thread will still be in a running state (and hence fepriv->thread is still set)
but the fepriv->exit field will still be zero.  As a result, if a
dvb_frontend_start() call arrives while the frontend thread is in the process
of terminating, the call will return 0 without actually starting a new thread.
This results in the tuning request being dropped.

To address this, mark fepriv->exit as soon as we know the thread is going to
be terminated, so that dvb_frontend_start() knows to start a new instance.

Problem encountered with Kaffeine 0.8.7 doing ATSC scanning against the
Pinnacle 801e tuner, in conjunction with new code to power down the xc5000
when not in use.
