4944e27d85 [media] gspca_sonixj: Enable more usb ids when sn9c102 gets compiled too
Both we and the windows driver make no sensor specific differences
(with some exceptions) for different sonixj bridge types. Thus if a
sn9c105 bridge has been successfully tested with a sensor, the same
sensor can be successfully used with a sn9c120 bridge too.

Using this knowledge we can move over most usb-ids too the sonixj
driver when both are compiled.

69ffd25457 [media] gspca_sonixb: Add usb ids for known sn9c103 cameras
Now that our bridge code is unified for sn9c101/102 and sn9c103 models,
the sn9c103 models should simply work, given that the only difference
in the sn9c103 is audio support and a gamma correction table.

a24f0c5c47 [media] sn9c102: Remove not supported and non existing usb ids
The sn9c102 driver claims a number of usb-ids which are for cameras
with sensor types which it does not support. Also it claims a number
of usb-ids which do not exist at all (not present in the windows
drivers .inf files, not known by google).

This patch also fixes the conflict with the gspca_sonixj driver for the
0c45:60c0 and 0c45:60fb usb ids.

8b064ee19d [media] et61x251: remove wrongly claimed usb ids
The et61x251 driver claims a whole list of usb id's, but it only has
one sensor "module" which does sensor detection based on usb id and that
only supports devices with the 102c:6251 usb id. Remove the usb-ids for
other devices as for those the driver will fail with an unable to determine
sensor type message anyways.

ee3629914b [media] gspca_main: Simplify read mode memory type checks
gspca_dev->memory == GSPCA_MEMORY_NO implies gspca_dev->nframes == 0,
so there is no need to check for both in dev_poll. The check in
dev_read also is more complex then needed, as dqbuf which dev_read
calls already does all necessary checks. Moreover dqbuf is holding
the proper locks while checking where as dev_read itself is not.

d642de2ed4 [media] gspca_main: Set memory type to GSPCA_MEMORY_NO on buffer release
Before this patch we were not setting the memory type to GSPCA_MEMORY_NO
when the buffers were released by the app doing a reqbufs 0. Nor would
the memory type be set to GSPCA_MEMORY_NO on device close, as capture_file
already is NULL on device close because of the reqbufs 0. This caused the
following problem:
-app1 does reqbufs USERPTR for 4 buffers
-app1 does reqbufs USERPTR for 0 buffers
-app2 tries to do reqbufs MMAP for 4 buffers
 fails because gspca_dev->memory still is USERPTR

Fixing this also allows an app to switch memory type's by unrequesting
the buffers and re-requesting them of a different type.

This patch also moves the setting of gspca_dev->frsz and gscpa_dev->memory
to after alloc_frame succeeding, so that they are not changed when allocating
fails.

Before this patch dqbuf errors out on a failing user_copy (with user pointers)
before updating the buffer flags, causing a successsfully dequeued buffer
to still have the DONE flag, which means that it could no longer be

27074efa2e [media] gspca_main: Locking fixes 2
Before this patch vidioc_dqbuf is using its own read_lock, where as
other queue related functions use queue_lock. This means that dqbuf is
accessing several variables in a racy manor. The most important one
being fr_o, which may be changed from underneath dqbuf by vidioc_reqbufs
or vidioc_streamoff. Other variables which it accesses unprotected
are gspca_dev->memory, gspca_dev->streaming and gspca_dev->capt_file.

This patch fixes this by changing vidioc_dqbuf to also use the queue_lock.

4e770f7602 [media] gspca_main: Locking fixes 1
The gspca_dev->streaming boolean is protected against multiple access
through gspca_dev->queue_lock everywhere except for 2 places. This patch
fixes this by bringing it under the lock in vidioc_streamoff. And by
removing the check for gspca_dev->streaming in gspca_disconnect,
the destroy_urbs call may be called multiple times (and is protected
by the usb_lock) and calling wake_up_interruptible can also always be done
safely.

f037484337 [media] tda9875: remove duplicate driver
In commit 411674fd18 the tda9875 support was
added to tvaudio. This means that tda9875 is no longer used since mid-2009.

If there are out-of-tree users of this driver, then they can switch to tvaudio
instead.

The original commit message read as follows:

    This change allows bttv to use tvaudio for this device. Since this device
    has the same i2c address as the tda9874 we need to support both in the same
    tvaudio driver. This makes it possible for tvaudio to detect which chip is
    used. Originally the tda9875 was only available in the dedicated tda9875
    driver, but that makes life very hard for bttv since loading tvaudio might
    misdetect a tda9875 as a tda9874.

So there were good reasons for moving the tda9875 code into tvaudio.

8fd0bda511 [media] em28xx: radio_fops should also use unlocked_ioctl
em28xx uses core assisted locking, so it shouldn't use .ioctl.
The .ioctl callback was replaced by .unlocked_ioctl for video nodes,
but not for radio nodes. This is now corrected.

46e67acd5d [media] wm8775: Revert changeset fcb9757333 to avoid a regression
It seems that cx88 and ivtv use wm8775 on some different modes. The
patch that added support for a board with wm8775 broke ivtv boards with
this device. As we're too close to release 2.6.37, let's just revert
it.

f23b7952d3 [media] cx25840: Prevent device probe failure due to volume control ERANGE error
This patch fixes a regression that crept into 2.6.36.

The volume control scale in the cx25840 driver has an unusual mapping
from register values to v4l2 volume control values.  Enforce the mapping
limits, so that the default volume control setting does not fall out of
bounds to prevent the cx25840 module device probe from failing.

e1e2c57565 [media] ivtv: Add Adaptec Remote Controller
lirc-i2c implements a get key logic for the Adaptec Remote
Controller, at address 0x6b. The only driver that seems to have
an Adaptec device is ivtv:

$ git grep -i adaptec drivers/media
drivers/media/video/cs53l32a.c: * cs53l32a (Adaptec AVC-2010 and AVC-2410) i2c ivtv driver.
drivers/media/video/cs53l32a.c: * Audio source switching for Adaptec AVC-2410 added by Trev Jackson
drivers/media/video/cs53l32a.c:   /* Set cs53l32a internal register for Adaptec 2010/2410 setup */
drivers/media/video/ivtv/ivtv-cards.c:/* Adaptec VideOh! AVC-2410 card */
drivers/media/video/ivtv/ivtv-cards.c:    { PCI_DEVICE_ID_IVTV16, IVTV_PCI_ID_ADAPTEC, 0x0093 },
drivers/media/video/ivtv/ivtv-cards.c:    .name = "Adaptec VideOh! AVC-2410",
drivers/media/video/ivtv/ivtv-cards.c:/* Adaptec VideOh! AVC-2010 card */
drivers/media/video/ivtv/ivtv-cards.c:    { PCI_DEVICE_ID_IVTV16, IVTV_PCI_ID_ADAPTEC, 0x0092 },
drivers/media/video/ivtv/ivtv-cards.c:    .name = "Adaptec VideOh! AVC-2010",
drivers/media/video/ivtv/ivtv-cards.h:#define IVTV_CARD_AVC2410         7 /* Adaptec AVC-2410 */
drivers/media/video/ivtv/ivtv-cards.h:#define IVTV_CARD_AVC2010         8 /* Adaptec AVD-2010 (No Tuner) */
drivers/media/video/ivtv/ivtv-cards.h:#define IVTV_PCI_ID_ADAPTEC                 0x9005
drivers/media/video/ivtv/ivtv-driver.c:            "\t\t\t 8 = Adaptec AVC-2410\n"
drivers/media/video/ivtv/ivtv-driver.c:            "\t\t\t 9 = Adaptec AVC-2010\n"
drivers/media/video/ivtv/ivtv-i2c.c:              0x6b,   /* Adaptec IR */

There are two Adaptec cards defined there, but AVC-2010 doesn't have a
remote controller. So, the logic at lirc_i2c seems to be for Adaptec AVC-2410.

As we'll remove lirc_i2c from kernel, move the getkey code to ivtv driver, and
use it for AVC-2410.
