If the USB driver is enabled but the demodulator is not, we get a link error: ERROR: "zd1301_demod_get_dvb_frontend" [drivers/media/usb/dvb-usb-v2/zd1301.ko] undefined! ERROR: "zd1301_demod_get_i2c_adapter" [drivers/media/usb/dvb-usb-v2/zd1301.ko] undefined! Such a configuration obviously makes no sense, but we should not fail the build. This tries to mimic what we have for other drivers by turning the build failure into a runtime failure. Alternatively we could use an unconditional 'select' or 'depends on' to enforce a sane configuration.

Commit 17ce039b ("[media] cxusb: don't do DMA on stack") added a kmalloc'ed bounce buffer for writes, but missed to do the same for reads. As the read only happens after the write is finished, we can reuse the same buffer. As dvb_usb_generic_rw handles a read length of 0 by itself, avoid calling it using the dvb_usb_generic_read wrapper function. Signed-off-by:

I ran into a stack frame size warning because of the on-stack copy of the USB device structure: drivers/media/usb/dvb-usb-v2/dvb_usb_core.c: In function 'dvb_usbv2_disconnect': drivers/media/usb/dvb-usb-v2/dvb_usb_core.c:1029:1: error: the frame size of 1104 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Copying a device structure like this is wrong for a number of other reasons too aside from the possible stack overflow. One of them is that the dev_info() call will print the name of the device later, but AFAICT we have only copied a pointer to the name earlier and the actual name has been freed by the time it gets printed. This removes the on-stack copy of the device and instead copies the device name using kstrdup(). I'm ignoring the possible failure here as both printk() and kfree() are able to deal with NULL pointers. Signed-off-by:

Hugues Fruchet authored
EOS (End Of Stream) support allows user to get all the potential decoded frames remaining in decoder pipeline after having reached the end of video bitstream. To do so, user calls VIDIOC_DECODER_CMD(V4L2_DEC_CMD_STOP) which will drain the decoder and get the drained frames that are then returned to user. User is informed of EOS completion in two ways: - dequeue of an empty frame flagged to V4L2_BUF_FLAG_LAST - reception of a V4L2_EVENT_EOS event. If, unfortunately, no buffer is available on CAPTURE queue to return the empty frame, EOS is delayed till user queue one CAPTURE buffer. Acked-by:

IPC (Inter Process Communication) support for communication with DELTA coprocessor firmware using rpmsg kernel framework. Based on 4 services open/set_stream/decode/close and their associated rpmsg messages. The messages structures are duplicated on both host and firmware side and are packed (use only of 32 bits size fields in messages structures to ensure packing). Each service is synchronous; service returns only when firmware acknowledges the associated command message. Due to significant parameters size exchanged from host to copro, parameters are not inserted in rpmsg messages. Instead, parameters are stored in physical memory shared between host and coprocessor. Memory is non-cacheable, so no special operation is required to ensure memory coherency on host and on coprocessor side. Multi-instance support and re-entrance are ensured using host_hdl and copro_hdl in message header exchanged between both host and coprocessor. This avoids to manage tables on both sides to get back the running context of each instance. Acked-by:

v4l2-async had several functions doing some operations and then not undoing the operations in a failure situation. For example, v4l2_async_test_notify() moved a subdev into notifier's done list even if registering the subdev (v4l2_device_register_subdev) failed. If the subdev was allocated and v4l2_async_register_subdev() called from the driver's probe() function, as usually, the probe() function freed the allocated subdev and returned a failure. Nevertheless, the subdev was still left into the notifier's done list, causing an access to already freed memory when the notifier was later unregistered. A hand-edited call trace leaving freed subdevs into the notifier: v4l2_async_register_notifier(notifier, asd) cameradrv_probe sd = devm_kzalloc() v4l2_async_register_subdev(sd) v4l2_async_test_notify(notifier, sd, asd) list_move(sd, ¬ifier->done) v4l2_device_register_subdev(notifier->v4l2_dev, sd) cameradrv_registered(sd) -> fails ->v4l2_async_register_subdev returns failure ->cameradrv_probe returns failure ->devres frees the allocated sd ->sd was freed but it still remains in the notifier's list. This patch fixes this and several other cases where a failing function could leave nodes into a linked list while the caller might free the node due to a failure.

There isn't an ioctl to enum the supported field orders, so a user-space application can call VIDIOC_TRY_FMT using different field orders to know if one is supported. For example, GStreamer does this so during playback dozens of the following messages appear in the kernel log buffer: [ 442.143393] Not supported field order(4) Instead of printing this as an error, just keep it as debug information.
