Casting the return value which is a void pointer is redundant. The conversion from void pointer to any other pointer type is guaranteed by the C programming language. Signed-off-by:

This is used by the I2C code in order to slow down the speed to 20 kHz on devices with xc5000 or xc5000c. So, it needs to be filled for all devices that use either xc5000 or xc5000c. Signed-off-by: -

Right now, the au0828 driver uses .tuner to detect if analog tv is being used or not. By not filling .tuner fields at the board struct, the I2C core can't do decisions based on it. So, add a field to explicitly tell when analog TV is supported. No functional changes. Signed-off-by: -

This comment is already at the au0828-i2c where it belongs. So, remove it from a board's entry. It doesn't make any sense there, as we're setting the clock to 250kHz there, slowing it down only at the au0828-i2c. Signed-off-by: -

cab_state->modulation is initialized with a wrong value: drivers/media/dvb-frontends/stv0367.c:3000:42: warning: mixing different enum types drivers/media/dvb-frontends/stv0367.c:3000:42: int enum fe_modulation versus drivers/media/dvb-frontends/stv0367.c:3000:42: int enum stv0367cab_mod as it was declared as "enum stv0367cab_mod". While it could be fixed, there's no value on it, as this is never used. So, just remove the modulation from cab_state structure. Signed-off-by: -

Instead of using a temporary stack allocated i2c_client in em28xx_i2c_ir_handle_key(), allocate/free the i2c_client at module init/uninit and hook it into struct em28xx_IR (if the device has an i2c IR decoder). This reduces the frame size of function em28xx_i2c_ir_handle_key() and speeds it up a bit. Also make sure that all fields of struct i2c_client are initialized properly. Signed-off-by:

The norm_swidth function was unused and is dropped. It's not clear what the purpose of that function was. The norm_maxh function was changed so it tests for 60 Hz standards rather than for 50 Hz standards. The is the preferred order. The norm_maxw function was poorly written and used: it gives the maximum allowed line width for the given standard. For 60 Hz that's 720, but for 50 Hz that's 768 which allows for 768x576 which gives you square pixels. For 60 Hz formats it is 640x480 that gives square pixels, so there is no need to go beyond 720. The initial width was set using norm_maxh(), which was wrong. Just set to 720, that's what you normally use. Since the initial standard was NTSC anyway the initial width was always 720 anyway.

Tested VBI support and discovered that the wrong offset was used. After this change it is now working. Verified with CC/XDS for NTSC and WSS/Teletext on PAL. It also reported the wrong start lines for the second field. That's now fixed as well. Signed-off-by:

Both adv7604 and adv7842 had the same typo in the code that sets the vertical backporch for the second interlaced field: it was assigned to vbackporch instead of il_vbackporch. In addition, the timings struct wasn't zeroed in the adv7842 driver, leaving several fields to undefined values causing the timing match function to fail. Signed-off-by:
-
Hans Verkuil authored
If one or both of the timings being compared have the standards field with value 0, then accept that. Only check for matching standards if both timings have actually filled in that field. Otherwise no match will ever be found since when timings are detected the standards field will typically be set to 0 by the driver. Signed-off-by:

This is useful to test teletext capture applications like alevt and mtt. It also fixes a previously undetected bug where the PAL VBI start line of the second field was off by one. Using the new field start defines helps a lot fixing such bugs. Signed-off-by:

A test in uvc_video_decode_isoc() checks whether an image has been received from the camera completely. For this the data amount is compared to the buffer length, which, however, doesn't have to be equal to the image size. Switch to using formats .sizeimage field for an exact expected image size.

The existing RGB555X pixel format is ill-defined in respect to its alpha bit and its meaning is driver dependent.

The uvcvideo webcam driver exposes the v4l2 control "Exposure (Absolute)" which allows the user to control the exposure time of the webcam, essentially controlling the brightness of the received image. By default the webcam automatically adjusts the exposure time automatically but the if you set the control "Exposure, Auto"="Manual Mode" the user can fix the exposure time. Unfortunately it seems that the Logitech C920 has a firmware bug where it will forget that it's in manual mode temporarily during initialisation. This means that the camera doesn't respect the exposure time that the user requested if they request it before starting to stream video. They end up with a video stream which is either too bright or too dark and must reset the controls after video starts streaming. This patch introduces the quirk UVC_QUIRK_RESTORE_CTRLS_ON_INIT which causes the cached controls to be re-uploaded to the camera immediately after initialising the camera. This quirk is applied to the C920 to work around this camera bug. Signed-off-by:

Map V4L2_CID_TILT_SPEED and V4L2_CID_PAN_SPEED to the standard UVC CT_PANTILT_RELATIVE_CONTROL terminal control request. Tested by plugging a Logitech ConferenceCam C3000e USB camera and controlling pan/tilt from the userspace using the VIDIOC_S_CTRL ioctl. Verified that it can pan and tilt at the same time in both directions. Signed-off-by:

It is possible to call STREAMON without having any buffers queued. So vb2_is_streaming() can return true without start_streaming() having been called. Only after at least one buffer has been queued will start_streaming be called. The check vb2_is_streaming() is incorrect as this would start the DMA without having proper DMA pointers set up. this patch uses vb2_start_streaming_called() instead to check is streaming was called.
