My initial thinking was that we should default to mouse mode, so people
could use the mouse function to click on something on a login screen,
but a lot of systems where a remote is useful automatically log in a
user and launch a media center application, some of which hide the
mouse, which can be confusing to users if they punch buttons on the
remote and don't see any feedback. Plus, first and foremost, its a
remote, so lets default to being a remote, and only toggle into mouse
mode when the user explicitly asks for it. As a nice side-effect, this
actually simplifies some of the code a fair bit...

The ene_ir driver was using a private define of MS_TO_NS, which is meant
to be microseconds to nanoseconds. The mceusb driver copied it,
intending to use is a milliseconds to microseconds. Lets move the
defines to a common location, expand and standardize them a touch, so
that we now have:
MS_TO_NS - milliseconds to nanoseconds
MS_TO_US - milliseconds to microseconds
US_TO_NS - microseconds to nanoseconds

There's a nasty bug that slipped in when the rc device interface was
altered, only affecting the older 0xffdc imon devices. We were trying
to access ictx->rdev->allowed_protos before ictx->rdev had been set.
There's also an issue with call ordering that meant the correct
keymap wasn't getting loaded for MCE IR type 0xffdc devices.

With cmwq, there's no reason to use separate out_work_queue. Drop it
and use system_wq instead. The in_work_queue needs to be ordered so
can't use one of the system wqs; however, as it isn't used to reclaim
memory, allocate the workqueue with alloc_ordered_workqueue() without
WQ_MEM_RECLAIM.

Hi,
While reading
drivers/media/video/tlg2300/pd-video.c::alloc_bulk_urbs_generic() I
noticed that
- We don't free the memory allocated to 'urb' if the call to
usb_alloc_coherent() fails.
- If the 'num' argument to the function is ever <= 0 we'll return an
uninitialized variable 'i' to the caller.
The following patch addresses both of the above by a) calling
usb_free_urb() when usb_alloc_coherent() fails and by explicitly
initializing 'i' to zero.
I also moved the variables 'mem' and 'urb' inside the for loop. This does
not actually make any difference, it just seemed more correct to me to let
variables exist only in the innermost scope they are used.

We may leak the storage allocated to 'state' in
drivers/media/dvb/frontends/ix2505v.c::ix2505v_attach() on error, as
it is too early to be able to call ix2505v_release().
This patch makes sure we free the allocated memory in the failure case.

Some subdevs need to call into the board code after they are registered
and have a valid struct v4l2_device pointer. The s_config op was abused
for this, but now that it is removed we need a cleaner way of solving this.
So this patch adds a struct with internal ops that the v4l2 core can call.
Currently only two ops exist: register and unregister. Subdevs can implement
these to call the board code and pass it the v4l2_device pointer, which the
board code can then use to get access to the struct that embeds the
v4l2_device.
It is expected that in the future open and close ops will also be added.

The core.s_config op was meant for legacy drivers that needed to work with old
pre-2.6.26 kernels. This is no longer relevant. Unfortunately, this op was
incorrectly called from several drivers.
Replace those occurences with proper i2c_board_info structs and call
v4l2_i2c_new_subdev_board.
After these changes v4l2_i2c_new_subdev_cfg() was no longer used, so remove
that function as well.

There are some weird bugs at tda8290/tda18271 initialization, as it

The problem is that mb86a20s is only visible if the analog part is disabled.
However, due to a trick at mb86a20s, it will later initialize properly:
mb86a20s: mb86a20s_initfe: Initialization succeded.
This is hacky and ugly. However, I coldn't find any easy way to fix it.
A proper fix would be to have a resource locking schema, used by both
V4L and DVB parts that would block access to analog registers while
digital registers are in use, but this will probably put tda829x into
a dead lock.

Due to a hard to track bug between tda829x/tda18271/saa7134, tda829x
wants to go to analog mode during DVB initialization, causing some
I2C errors.
The analog failure doesn't cause any harm, as the device were already
properly initialized in analog mode. However, the failure at the digital
mode causes the frontend mb86a20s to not initialize. Fortunately, at
least on my tests, it was possible to detect that the device is a
mb86a20s before the failure.
What happens is that tda8290 is a very bad boy: during DVB setup, it
keeps insisting to call tda18271 analog_set_params, that calls
tune_agc code. The tune_agc code calls saa7134 driver, changing the
value of GPIO 27, switching from digital to analog mode and disabling
the access to mb86a20s, as, on Kworld SBTVD, the same GPIO used
to switch the hardware AGC mode seems to be used to enable the I2C
switch that allows access to the frontend (mb86a20s).
So, a call to analog_set_params ultimately disables the access to
the frontend, and causes a failure at the init frontend logic.
This patch is a workaround for this issue: it simply checks if the
frontend init had any failure. If so, it will init the frontend when
some DTV application will try to set DVB mode.
Even being a hack for Kworld SBTVD to work, and assumning that we could
teach tda8290 to be a good boy, this is actually an improvement at the
frontend driver, as it will be more reliable to initialization failures.

Fixes Fedora 14 bug: https://bugzilla.redhat.com/show_bug.cgi?id=667157
There are a few bugs at the code that generates the scancode at dib0700:
- RC keycode is wrong (it outputs a 24 bits keycode);
- NEC extended outputs a keycode that have endiannes issues;
- keycode tables for NEC extended remotes need to be updated.
The last issue need to be done as we get reports, as we don't have
the complete NEC-extended keycodes at the dibcom table.

Looking at the windows inf file, for usb ids with a sensor type where probing
is needed to determine the type (for example ov7630 or soi768), this is
needed for all bridge variants with a usb id indicating this sensor type.
So do the probing to determine the actual sensor type for types where the
usb-id info is not 100% deterministic, independent of the bridge type.
If you look through the list of currently active usb ids in sonixj, this
effectively only changes the code path for 0c45:60fe (sn9c105 + ov7630) and
0c45:612e (sn9c110 + ov7630), which according to the inf file can have a
soi768 instead of a ov7630 just like the sn9c120 + ov7630 models where we
already probe for a soi7630.
The main reason for this code change is to keep the code paths as bridge
variant independent as possible, so that we don't need a lot of special
per bridge cases, as we enable more usb-ids in the future.
This change makes the 0c45:60fe code path identical to the successfully
tested 0c45:613e, so also make sonixj the default driver for 0c45:60fe.

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.

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.

Refactor the code to unify how the sn9c101/102 and the sn9c103 bridge
are handled. Also move code which is the same for all sensors from
the per sensor init register settings to a central place.

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.

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.

We check for not streaming as a condition to abort waiting in dqbuf, so
when another thread does a streamoff we should wake the wq.

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.
