Reading registers from the pcear USB dongles with the si470x causes a
loud pop (and an alsa buffer overrun). Since most radio apps periodically
call G_TUNER to update mono/stereo, signal and afc status this leads
to the music . pop . music . pop . music -> not good.
On the internet there is an howto for flashing the pcear with a newer
firmware from the silabs reference boardto fix this, but:
1) This howto relies on a special version of the driver which allows
firmware flashing
2) We should try to avoid the answer to a bug report being upgrade your
firmware, if at all possible
3) Windows does not suffer from the pop sounds
After a quick look at the driver I found at that the register reads are
not necessary at all, as the device gives us the necessary status through
usb interrupt packets, and the driver already uses these!

introduced an additional bit flag (V4L2_FL_LOCK_ALL_FOPS) that
should be set by drivers that use the v4l2 core lock for all file

[media] cx25840: fix regression in HVR-1800 analog support
The refactoring of the cx25840 driver to support the cx23888 caused breakage
with the existing support for cx23885/cx23887 analog support. Rework the
routines such that the new code is only used for the 888.
Validated with the following boards:
HVR-1800 retail (0070:7801)
HVR-1800 OEM (0070:7809)
HVR_1850 retail (0070:8541)
Thanks to Steven Toth and Hauppauge for loaning me various boards to
regression test with.

[media] cx231xx: don't DMA to random addresses
Commit
7a6f6c29d264cdd2fe0eb3d923217eed5f0ad134 (cx231xx: use
URB_NO_TRANSFER_DMA_MAP) was intended to avoid mapping the DMA buffer
for URB twice. This works for the URBs allocated with usb_alloc_urb(),
as those are allocated from cohernent DMA pools, but the flag was also
added for the VBI and audio URBs, which have a manually allocated area.
This leaves the random trash in the structure after allocation as the
DMA address, corrupting memory and preventing VBI and audio from
working. Letting the USB core map the buffers solves the problem.

[media] bttv-cards.c: Allow radio for CHP05x/CHP06x
Add ".has_radio = 1" for BTTV_BOARD_MAGICTVIEW061 because there are
some CHP05x/CHP06x boards with a radio tuner.
I still have an analog Askey Magic TView card (CHP051, PCI 144f:3002)
which I use for radio only. This worked fine with kernel 2.6.37
(openSUSE 11.4), but no longer works with kernel 3.1.10 (openSUSE 12.1).
The reason apparently is that ".has_radio = 1" is missing in
bttv-cards.c for BTTV_BOARD_MAGICTVIEW061; when I add this line and
recompile the kernel, radio is working again. The line is still missing
in the latest git tree, for which I have generated the attached patch.
I can't test what will happen for CHP05x/CHP06x devices without radio;
however, it seems that other cards also have the problem that there are
some boards with radio and some without, so I hope that this can be
sorted out.

[media] uvcvideo: Fix frame drop in bulk video stream
When video endpoint is configured as bulk, a ZLP is sent after every
video frames with size as multiple of 512 bytes. This is done so that
host can detect end of transfer and pass data for processing.
Still, frames that are multiple of 16K in size gets dropped. The ZLP
sent by camera is ignored by uvc_video_decode_bulk(). The makes sure
that the ZLP is not part of a video frame before ignoring it. If ZLP
follows a video frame, then it triggers completion callback.

[media] uvcvideo: Document the struct uvc_xu_control_query query field
Several developers have reported that the lack of macros for the struct
uvc_xu_control_query query field in uvcvideo.h was confusing and forced
them to look at the driver source code to find out what applications
were supposed to pass in that field.
Add a comment to the header to clarify the expected usage of the query
field.
