clear of the output_specs before passing it to the configure_resizer_out_params(), so that no garbage values are set. This fixes following build warning: drivers/staging/media/davinci_vpfe/dm365_resizer.c: In function 'resizer_set_stream': drivers/staging/media/davinci_vpfe/dm365_resizer.c:190:46: warning: 'output_specs.vst_c' may be used uninitialized in this function [-Wmaybe-uninitialized] param->ext_mem_param[index].rsz_sdr_ptr_s_c = output->vst_c; ^ drivers/staging/media/davinci_vpfe/dm365_resizer.c:316:30: note: 'output_specs.vst_c' was declared here struct vpfe_rsz_output_spec output_specs; ^ Signed-off-by: -

We need own I2C locking because of tuner I2C adapter/repeater. Firmware command is executed using I2C send + reply message. Default I2C adapter locking protects only single I2C operation, not whole send + reply sequence as needed. Due to that, it was possible tuner I2C message interrupts firmware command sequence.

The changeset dc9ef7d1 change the open() ioctl documentation to match the V4L2 open(). However, some cut-and-pasted stuff doesn't match what actually happens at the DVB core. So, fix the documentation entry to be more accurate with the DVB frontend open() specifics. Signed-off-by:

The UVC_DEV_DISCONNECTED flag is set when the USB device is disconnected, and checked in the open() handler to refuse opening a device that has been disconnected. This is inherently racy, but the race condition is taken care of in the V4L2 core, which also fails open() calls when the V4L2 device node has been unregistered. As the uvcvideo USB disconnect handler unregisters all its video device nodes, the UVC_DEV_DISCONNECTED flag doesn't serve any purpose anymore and can be removed. Signed-off-by:

The "TOSHIBA Web Camera - 5M" Chicony device (04f2:b50b) seems to compute the bandwidth on 16 bits and erroneously sign-extend it to 32 bits, resulting in a huge bandwidth value. Detect and fix that condition by setting the 16 MSBs to 0 when they're all equal to 1. Reported-by:

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate. Signed-off-by:

When stop_streaming is called while a frame is currently being retrieved, the buffer being filled will still be returned with BUF_STATE_DONE. By resetting the sequence number and checking before returning the buffer, it can now correctly be returned with BUF_STATE_ERROR. Signed-off-by:

Add missing functions to query the single fixed frame size (960x540) and supported frame rates. Technically, the SUR40 supports any arbitrary frame rate up to 60 FPS, as it is polled and not interrupt-driven. For now, we just report 30 and 60 FPS, which is sufficient to make most V4L2 tools work. Signed-off-by:

Florian Echtler authored
The SUR40 hardware can deliver images at up to 60 FPS; at full USB2 bandwidth, one raw frame will take about 11 ms to transmit. If the poll interval is above 5 ms, fully handling one frame will take longer than 16 ms and the overall frame rate will drop below 60 FPS. To get the full frame rate without blocking all the time and still allowing for a bit of timing jitter, we reduce the poll interval to 4 ms. Signed-off-by:

The mapping of COLORSPACE_DEFAULT, YCBCR_ENC_DEFAULT or QUANTIZATION_DEFAULT to proper non-default values is fairly complex, and it is something that needs to be done both in the kernel and in userspace. So add macros that can do this conversion, making this available to both kernel and userspace. Signed-off-by:

Hans Verkuil authored
V4L2_COLORSPACE_DEFAULT is added so we have a specific define for the default case where applications do not set it but leave it to 0. In that case the driver will set the colorspace based on what it captures. This is already used, but we never had a define for the value 0. Signed-off-by:

The log_status ioctl should report if the audio input has mode Bilingual. However, the check against the itv->dualwatch_stereo_mode is completely wrong and is a left-over from the distant past. Not only is the bitmask obviously wrong, the test itself is broken too since itv->dualwatch_stereo_mode is no longer a bitmask at all. Fix this code properly. Signed-off-by:
