lirc: wire up .compat_ioctl to main ioctl handler
As pointed out (and tested) by Joris van Rantwijk, we do actually need
to wire up .compat_ioctl for 32-bit lirc userspace to work with 64-bit
lirc kernelspace. Do it. And add a check to make sure we get a valid
irctl in the ioctl handler.

IR/lirc: further ioctl portability fixups
From: Joris van Rantwijk <jorispubl@xs4all.nl>
----8<----
I tested lirc_serial and found that it works fine.
Except the LIRC ioctls do not work in my 64-bit-kernel/32-bit-user
setup. I added compat_ioctl entries in the drivers to fix this.
While doing so, I noticed inconsistencies in the argument type of
the LIRC ioctls. All ioctls are declared in lirc.h as having argument
type __u32, however there are a few places where the driver calls
get_user/put_user with an unsigned long argument.
The patch below changes lirc_dev and lirc_serial to use __u32 for all
ioctl arguments, and adds compat_ioctl entries.
It should probably also be done in the other low-level drivers,
but I don't have hardware to test those.
----8<----
I've dropped the .compat_ioctl addition from Joris' original patch,
as I swear the non-compat definition should now work for both 32-bit
and 64-bit userspace. Technically, I think we still need/want a
Signed-off-by: from Joris here. Joris? (And sorry for the lengthy delay
in getting a reply to you).

commit 611225f5e7f9d11c4b119fac224f1bd6903b0150
Author: Jarod Wilson <jarod@redhat.com>
Date: Sun Mar 7 17:55:43 2010 -0300
V4L/DVB: dvb: add support for kworld 340u and ub435-q to em28xx-dvb
This adds support for the KWorld PlusTV 340U and KWorld UB345-Q ATSC
sticks, which are really the same device. The sticks have an eMPIA
em2870 usb bridge chipset, an LG Electronics LGDT3304 ATSC/QAM
demodulator and an NXP TDA18271HD tuner -- early versions of the 340U
have a a TDA18271HD/C1, later models and the UB435-Q have a C2.
The stick has been tested succesfully with both VSB_8 and QAM_256 signals.
Its using lgdt3304 support added to the lgdt3305 driver by a prior patch,
rather than the current lgdt3304 driver, as its severely lacking in
functionality by comparison (see said patch for details).

From: Jarod Wilson <jarod@redhat.com>

Subject: [PATCH 1/2] dvb: add lgdt3304 support to lgdt3305 driver
There's a currently-unused lgdt3304 demod driver, which leaves a lot to
be desired as far as functionality. The 3304 is unsurprisingly quite
similar to the 3305, and empirical testing yeilds far better results
and more complete functionality by merging 3304 support into the 3305
driver. (For example, the current lgdt3304 driver lacks support for
signal strength, snr, ucblocks, etc., which we get w/the lgdt3305).
For the moment, not dropping the lgdt3304 driver, and its still up to
a given device's config setup to choose which demod driver to use, but
I'd suggest dropping the 3304 driver entirely.
As a follow-up to this patch, I've got another patch that adds support
for the KWorld PlusTV 340U (ATSC) em2870-based tuner stick, driving
its lgdt3304 demod via this lgdt3305 driver, which is what I used to
successfully test this patch with both VSB_8 and QAM_256 signals.
A few pieces are still a touch crude, but I think its a solid start,
as well as much cleaner and more feature-complete than the existing
lgdt3304 driver.

Subject: [media] imon: fix my egregious brown paper bag w/rdev/idev split

[media] imon: fix my egregious brown paper bag w/rdev/idev split
Somehow, I managed to screw things up when reworking the rdev/idev split
patch from David, and started trying to get ir_input_dev from idev
instead of rdev, thus resulting in button presses hanging the system.
This fixes it.

lirc_dev: fixes in lirc_dev_fop_read()
This makes several changes but they're in one function and sort of
related:
"buf" was leaked on error. The leak if we try to read an invalid
length is the main concern because it could be triggered over and
over.
If the copy_to_user() failed, then the original code returned the
number of bytes remaining. read() is supposed to be the opposite way,
where we return the number of bytes copied. I changed it to just return
-EFAULT on errors.
Also I changed the debug output from "-EFAULT" to just "<fail>" because
it isn't -EFAULT necessarily. And since we go though that path if the
length is invalid now, there was another debug print that I removed.

rc: fix sysfs entry for mceusb and streamzap
When trying to create persistent device names for mceusb and streamzap
devices, I noticed that their respective drivers are not creating the rc
device as a child of the USB device. Rather it creates it as virtual
device. As a result, udev cannot use the USB device information to
create persistent device names for event and lirc devices associated
with the rc device. Not having persistent device names makes it more
difficult to make use of the devices in userspace as their names can
change.

streamzap: merge timeout space with trailing space
There are cases where we get an ending space, and our trailing timeout
space then gets sent right after it, which breaks repeat, at least for
lirc userspace decoding. Merge the two spaces by way of using
ir_raw_event_store_filter, set a timeout value, and we're back to good.
Successfully tested with streamzap and windows mce remotes.

[media] mceusb: fix keybouce issue after parser simplification
Something I failed to notice while testing the mceusb RLE buffer
decoding simplification patches was that we were getting an extra event
from the previously pressed key.
As was pointed out to me on irc by Maxim, this is actually due to using
ir_raw_event_store_with_filter without having set up a timeout value.
The hardware has a timeout value we're now reading and storing, which
properly enables the transition to idle in the raw event storage
process, and makes IR decode behave correctly w/o keybounce.
Also remove no-longer-used ir_raw_event struct from mceusb_dev struct
and add as-yet-unused enable flags for carrier reports and learning
mode, which I'll hopefully start wiring up sooner than later. While
looking into that, found evidence that 0x9f 0x15 responses are only
non-zero when the short-range learning sensor is used, so correct the
debug spew message, and then suppress it when using the standard
long-range sensor.

According to the v4l2 spec, writing any value to a button control should
result in the action belonging to the button control being triggered.
UVC cams however want to see a 1 written, this patch fixes this by

uvcvideo: Support menu controls in the control mapping API
The UVCIOC_CTRL_MAP ioctl doesn't support menu entries for menu
controls. As the uvc_xu_control_mapping structure has no reserved
fields, this can't be fixed while keeping ABI compatibility.
Modify the UVCIOC_CTRL_MAP ioctl to add menu entries support, and define
UVCIOC_CTRL_MAP_OLD that supports the old ABI without any ability to add
menu controls.
