7bd444ede7 [media] TM6000: Clean-up i2c initialization
Usage of templates for large structures is a bad idea, as it wastes a
lot of space. Manually initializing the few fields we need is way more
efficient.

Also set the algorithm data const, use strlcpy instead of strcpy, fix
a small race (device data must always be set before registering said
device) and properly return error on adapter registration failure.

8ea43d0a2f [media] rc: Remove ir-common module
Now, just one old bttv board uses the old RC5 raw decoding routines.
Its conversion to rc-core requires the generation of IRQ data for both
positive and negative transitions at the IRQ line. I'm not sure if
bttv driver supports it or if the transitions will be reliable enough.
So, due to the lack of hardware for testing, the better for now is to
just move the legacy routines to bttv driver, and wait for someone with
a Nebula Digi could help to port it to use also rc-core raw decoders.

c0b33bdc5b [media] gspca-stv06xx: support bandwidth changing
stv06xx devices have only one altsetting, but the actual used
bandwidth can be programmed through a register. We were already
setting this register lower then the max packetsize of the altsetting
indicates. This patch makes the gspca-stv06xx update the usb descriptor
for the alt setting to reflect the actual packetsize in use, so that
the usb subsystem uses the correct information for scheduling usb transfers.

This patch also tries to fallback to lower speeds in case a ENOSPC error
is received when submitting urbs, but currently this is only supported
with stv06xx cams with the pb0100 sensor, as this is the only one for
which we know how to change the framerate.

This patch is based on an initial incomplete patch by

0e72cc8b8d [media] saa7164: make buffer smaller
This isn't a runtime bug, it's just to make static checkers happy.

In vidioc_querycap() we copy a saa7164_dev ->name driver array into a
v4l2_capability -> driver array.  The ->driver array is only 16 chars
long so ->name also can't be more than 16 characters.

The ->name gets set in v4l2_capability() and it always is less than 16
characters so we can easily make the buffer smaller.

2eb2583277 [media] ir-kbd-i2c: add rc_dev as a parameter to the driver
There are several fields on rc_dev that drivers can benefit. Allow drivers
to pass it as a parameter to the driver.

For now, the rc_dev parameter is optional. If drivers don't pass it, create
them internally. However, the best is to create rc_dev inside the drivers,
in order to fill other fields, like open(), close(), driver_name, etc.
So, a latter patch making it mandatory and changing the caller drivers is
welcome.

d8b4b5822f [media] ir-core: make struct rc_dev the primary interface
This patch merges the ir_input_dev and ir_dev_props structs into a single
struct called rc_dev. The drivers and various functions in rc-core used
by the drivers are also changed to use rc_dev as the primary interface
when dealing with rc-core.

This means that the input_dev is abstracted away from the drivers which
is necessary if we ever want to support multiple input devs per rc device.

The new API is similar to what the input subsystem uses, i.e:
rc_device_alloc()
rc_device_free()
rc_device_register()
rc_device_unregister()

[mchehab@redhat.com: this patch were originally bundled with some renaming

Instead of using the original approach, I wrote the rename patches and the

to merge upstream, especially if some conflict rises on the renaming patches]

saa7134 (ir_rc5_timer_end is the only function exported by

2997137be8 [media] ir-core: convert drivers/media/video/cx88 to ir-core
This patch converts the cx88 driver (for sampling hw) to use the
decoders provided by ir-core instead of the separate ones provided
by ir-functions (and gets rid of those).

The value for MO_DDS_IO had a comment saying it corresponded to
a 4kHz samplerate. That comment was unfortunately misleading. The
actual samplerate was something like 3250Hz.

The current value has been derived by analyzing the elapsed time
between interrupts for different values (knowing that each interrupt
corresponds to 32 samples).
