997ea58eb9 USB: rename usb_buffer_alloc() and usb_buffer_free() users
For more clearance what the functions actually do,

  usb_buffer_alloc() is renamed to usb_alloc_coherent()
  usb_buffer_free()  is renamed to usb_free_coherent()

They should only be used in code which really needs DMA coherency.

All call sites have been changed accordingly, except for staging
drivers.

D'oh. Okay, here's v2, should fix that buglet too.

This hack was used when the imon driver was using internal key lookup
routines, but became dead weight when the driver was converted to use
ir-core's key lookup routines. These bits simply didn't get removed,
drop 'em now.

Pointed out by Dan Carpenter.

v2: fix possible attempt to access beyond end of key table array,
also pointed out by Dan.

If there are users (for example users == -2) :

 - 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.

8b661b508b V4L/DVB: s2255drv: remove dead code
My concern initially was we dereference "dev" in the parameter list to
s2255_dev_err() but it turns out that code path is never used.
The s2255_stop_readpipe() is only called from one place and "dev" is
never null.  So this patch just removes the whole condition here.

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.

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).

33ddc16f10 V4L/DVB: gspca - sn9c20x: HAS_BUTTON flag -> HAS_NO_BUTTON flag
Reverse HAS_BUTTON logic since most webcams either have a button or if
they don't don't bother to send any interrupts. However I have at least
one model that appears to leave the button GPIO floating and can send
a bogus interrupt.

f2b305cd67 V4L/DVB: hdpvr: fix disconnect sequence
Disconnecting the HDPVR caused a kernel oops if lockdep was enabled.
In addition, if an app still had video0 open and attempted to call ioctl
when the device was already disconnected the system would crash.

Move the freeing and cleanup code to the release function: that is the
right place for it since you know when you get there that nobody is
using the device.

Also removed usb_set_intfdata: v4l2_device_register sets this already
to v4l2_dev.

cf19cd3d8a V4L/DVB: tvp7002: fix query_dv_preset
If no signal or valid format is detected, then VIDIOC_QUERY_DV_PRESET must
return 0 and set the preset to V4L2_DV_INVALID.

This driver returned an error instead.

Also simplified the kernel messages a bit: change v4l2_err to v4l2_dbg (not
detecting a signal/valid format is not an error, so only print this info when
debug == 1) and do not call v4l_fill_dv_preset_info: it's overkill to do this
just for a debug message.

Thanks to Mats Randgaard for bringing this to my attention.

ffb4877ba0 V4L/DVB: v4l2-common: simplify prio utility functions
v4l2_prio_init/open/close returned an int when in fact they would
always return 0. Make these void functions.

v4l2_prio_close and v4l2_prio_check pass an enum v4l2_priority as a
pointer for no good reason. Replace with a normal enum v4l2_priority
argument.

These changes will simplify the work of moving priority handling into
the v4l core.
