If my dvb device is removed while in use, I got the following oops:

If there are users (for example users == -2) :
 - dvb_unregister_frontend :
 - stop kernel thread with dvb_frontend_stop :
  - fepriv->exit = 1;
  - thread loop catch stop event and break while loop
  - fepriv->thread = NULL; and fepriv->exit = 0;
 - dvb_unregister_frontend wait on "fepriv->dvbdev->wait_queue" that fepriv->dvbdev->users==-1.
The user finish :
 - dvb_frontend_release - set users to -1
 - don't wait wait_queue because fepriv->exit != 1

=> dvb_unregister_frontend never exit the wait queue.

Start moving the dvb specific code to ngene-dvb.c.  Note that there is still
stuff in ngene-core.c which could potentially be moved out, but it will require

Note that this patch makes *no* functional change - all I did was cut/paste the

Devin Heitmueller fdafc96c91 V4L/DVB: ngene: properly support boards where channel 0 isn't a TS input
The current code assumes that channel zero is always a TS input, which would
result in an oops if the "one_adapter" modprobe option is 1 (which it is by
default) and the board in question has something else on channel zero (which
is the case for the Avermedia m780, which has it's analog input wired to UVI1)

The code now explicitly tracks the first adapter created and ensures that
other channels cannot accidentially be associated with a NULL adapter.

Also, eliminate what appears to be a typo where all of the channel parameters
are getting associated with stream zero's properties, which will work if you
happen to have a dual stream board with the exact same configuration, but if
they differ then the second stream is going to end up with the first stream's
configuration.

Dan Carpenter 32ec4576c3 V4L/DVB: media/az6027: doing dma on the stack
I changed the dma buffers to use allocated memory instead of stack
memory.

The reason for this is documented in Documentation/DMA-API-HOWTO.txt
under the section:  "What memory is DMA'able?"  That document was only
added a couple weeks ago and there are still lots of modules which
haven't been corrected yet.  Btw. Smatch includes a pretty good test to
find places which use stack memory as a dma buffer.  That's how I found
these.  (http://smatch.sf.net).

The enum fe_caps provides flags that allow an application to detect

A flag for detecting PSK_8, however, is missing.
This patch adds the flag FE_CAN_PSK_8 to frontend.h and implements
it for the gp8psk-fe.c and cx24116.c driver (apparently the only ones
with PSK_8). Only the gp8psk-fe.c has been explicitly tested, though.

Abylay Ospan ab6a21f363 V4L/DVB: Allow to enable TS continuity and TEI check on loaded module
Current dvb_demux_tscheck processing doesn't allow to enable check on loaded
module. dvb_demux_tscheck can be enabled only when loading module (
dvb_dmx_init should be called to enable dvb_demux_tscheck ). This patch fix
this issue.

Henrik Kurelid ad5e9b9b7d V4L/DVB: firedtv: correct version number and current/next in CA_PMT
The version number in the CA_PMT message sent to the hardware was
alwaysed set to zero. This could cause problems if the PMT would
change during decryption of a channel since the new CA_PMT would have
the same version number as the old. The version number is now copied
from the original PMT.

Devin Heitmueller b628a2a3d4 V4L/DVB: au8522: fix case where we don't perform the first tune after going digital
Address a problem found in MythTV where if we are in digital mode, switch to
analog mode, and the switch back to digital mode, the first tuning request
after switching back to digital mode gets dropped.  This is because the au8522
maintains internal state, and would think the demod was already tuned to the
target frequency.

Thanks to Zaphod Beeblebrox for reporting this issue.
