Carry struct i2c_client pointer inside struct dvb_frontend private pointer. This driver is I2C driver, which is represented as a struct i2c_client, so better to carry this top level structure for each routine in order to unify things. This allows further simplification. Signed-off-by:

Add support for controlling TP clock mode for VSB and QAM annex-B/C mode. Gated clock mode is the default value, and does not support QAM annex-C. The patch enables setting this control to fixed clock mode. Signed-off-by:

I found a problem on vc032x gspca usb webcam subdriver: "bytesperline" property is wrong for YUYV and YVYU formats. With recent v4l-utils library (>=0.9.1), that uses "bytesperline" for pixel format conversion, the result is a wrong jerky image. Patch tested on my laptop (USB webcam Logitech Orbicam 046d:0892).

"n" is a user controlled integer. The code here doesn't handle the case where "n" is negative and this causes a static checker warning. drivers/media/usb/gspca/gspca.c:1571 vidioc_s_parm() warn: no lower bound on 'n' parm.capture.readbuffers is unsigned, so make n unsigned too, fixing this.

Add support in the PS3 Eye driver for QVGA capture at higher frame rates: 187, 150, and 137 FPS. This functionality is valuable because the PS3 Eye is popular for computer vision projects and no other camera in its price range supports such high frame rates. Correct a QVGA mode that was listed as 40 FPS. It is really 37 FPS (half of 75 FPS). Tests confirm that the nominal frame rates are achieved. Signed-off-by:

If start_streaming fails, then the buffers must be given back to vb2 with state QUEUED, not ERROR. Otherwise a WARN_ON will be generated. In the disconnect it is pointless to call pwc_cleanup_queued_bufs() as stop_streaming() will be called anyway. Signed-off-by:

Add support for the larger fifo found on sun5i and sun6i, having a separate compatible for the ir found on sun5i & sun6i also is useful if we ever want to add ir transmit support, because the sun5i & sun6i version do not have transmit support. Note this commits also adds checking for the end-of-packet interrupt flag (which was already enabled), as the fifo-data-available interrupt flag only gets set when the trigger-level is exceeded. So far we've been getting away with not doing this because of the low trigger-level, but this is something which we should have done since day one. Signed-off-by:

When converting to or from Y'CbCr and R'G'B' the Y offset depends on the quantization range: it's 0 for full and 16 for limited range. But in the code it was hardcoded to 16. This messed up the brightness of the generated pattern. Signed-off-by:

This reverts commit 18661234. The video_device debug field has been renamed to dev_debug, resulting in a compilation failure. As v4l2 debugging is supposed to be controlled through a sysfs attribute created by the v4l2 core, there's no need to duplicate debug control through a module parameter. Remove it. Signed-off-by:

The UVC spec is a bit vague wrt devices using bulk endpoints, specifically, how to signal to a device to start streaming. For devices using isoc endpoints, the sequence for start streaming is: 1) The host sends PROBE_CONTROL(SET_CUR) PROBE_CONTROL(GET_CUR) 2) Host selects desired config and calls COMMIT_CONTROL(SET_CUR) 3) Host selects an alt interface other then zero - e.g SELECT_ALTERNATE_INTERFACE(1) 4) The device starts streaming However for devices using bulk endpoints, there must be *no* alt interface other than setting zero. From the UVC spec: "A VideoStreaming interface containing a bulk endpoint for streaming shall support only alternate setting zero. Additional alternate settings containing bulk endpoints are not permitted in a device that is compliant with the Video Class specification." So for devices using bulk endpoints, step #3 above is irrelevant, and thus cannot be used as an indication for the device to start streaming. So in practice, such devices start streaming immediately after a COMMIT_CONTROL(SET_CUR). In the uvc resume() handler, an unsolicited commit is sent, which causes devices using bulk endpoints to start streaming unintentionally. This patch modifies resume() handler to send a commit only if streaming needs to be reestablished, i.e if the device was actually streaming before is was suspended. Signed-off-by:

When receiving video it is very useful to be able to unpack the InfoFrames. Logging is useful as well, both for transmitters and receivers. Especially when implementing the VIDIOC_LOG_STATUS ioctl (supported by many V4L2 drivers) for a receiver it is important to be able to easily log what the InfoFrame contains. This greatly simplifies debugging. Signed-off-by:

The "i" variable is used as an offset into both the dev->vfd[] and the dev->devtype->vdevs[] arrays. The second array is smaller so we should use that as a limit instead of ARRAY_SIZE(dev->vfd). Also the original check was off by one. We should use a format string as well in case the ->name has any funny characters and also to stop static checkers from complaining. Signed-off-by:

Remove tea575x-specific code from bttv and use the common driver instead. Only set_frequency is implemented (signal/stereo detection or seek would require more changes to bttv). It works fine on Video Highway Xtreme (it actually makes the radio usable as it currently cannot be tuned properly). Miro/Pinnacle is untested but seems to be simple and should work. However, I don't understand the Terratec Active Radio Upgrade code. The HW seems to need IOR, IOW and CSEL signals that were taken from ISA bus on older cards (IOR and IOW directly and CSEL from some address decoder) and are emulated here using GPIOs. But the code manipulating these signals in bttv seems to be broken - it never asserts the IOR signal. If anyone has this HW, please test if I got that right. Signed-off-by:
