Currently compound controls do not have a simple way of initializing its values. This results in ofuscated code with type_ops init. This patch introduces a new field on the control with the default value for the compound control that can be set with the brand new v4l2_ctrl_new_std_compound function Suggested-by:

If a subdevice is unregistered and then registered again without the driver being removed and re-probed (which will happen when the media device is removed and re-probed without also removing/re-probing the subdevice), media_device_register_entity() is called with a non-zero entity->num_pads, and then the subdevice's .registered callback calls media_entity_pads_init(). Thus the subdevice's pad objects are added to the media device pad list twice, causing list corruption. One way to fix this would be to create media_entity_pads_destroy(), and call it in the subdevice's .unregistered callback. But calling media_entity_pads_init() in the .registered callbacks was done for legacy reasons and is no longer necessary, so move the call to media_entity_pads_init() into the subdevice's probe functions. This fixes the duplicate pad obejcts in the media device pad list. Signed-off-by:

If the CSI is unregistered and then registered again without the driver being removed and re-probed (which will happen when the media device is removed and re-probed without also removing/re-probing the CSI), the result is the kobject error and backtrace "tried to init an initialized object". This is because the video device is left in an initialized state after being unregistered, thus the video device's underlying kobject is also left in an initialized state when the device is registered again. Fix this by moving imx_media_capture_device_init() and _remove() into csi_registered() and csi_unregistered(). This will create a new un-initialized video device when the CSI is re-registered. Do this for all the subdevices that register a capture device. Reported-by:

Visual inspection of the usbvision driver shows that it suffers from three races between its open, close, and disconnect handlers. In particular, the driver is careful to update its usbvision->user and usbvision->remove_pending flags while holding the private mutex, but: usbvision_v4l2_close() and usbvision_radio_close() don't hold the mutex while they check the value of usbvision->remove_pending; usbvision_disconnect() doesn't hold the mutex while checking the value of usbvision->user; and also, usbvision_v4l2_open() and usbvision_radio_open() don't check whether the device has been unplugged before allowing the user to open the device files. Each of these can potentially lead to usbvision_release() being called twice and use-after-free errors. This patch fixes the races by reading the flags while the mutex is still held and checking for pending removes before allowing an open to succeed. Signed-off-by:

The syzbot fuzzer found two invalid-access bugs in the usbvision driver. These bugs occur when userspace keeps the device file open after the device has been disconnected and usbvision_disconnect() has set usbvision->dev to NULL: When the device file is closed, usbvision_radio_close() tries to issue a usb_set_interface() call, passing the NULL pointer as its first argument. If userspace performs a querycap ioctl call, vidioc_querycap() calls usb_make_path() with the same NULL pointer. This patch fixes the problems by making the appropriate tests beforehand. Note that vidioc_querycap() is protected by usbvision->v4l2_lock, acquired in a higher layer of the V4L2 subsystem.

Add support for the PCI hybrid card NotOnlyTV LV3H. This card consists of: - A/V Controller: Conexant CX-23883 - Tuner: Xceive XC3028L - DVB-T Decoder: Zarlink ZL10353 This patch adds support for DVB-T, Analog TV, FM radio, composite and S-video inputs. The IR input isn't supported. Since the PCI subsystem ID (14f1:8852) is the same as the Geniatech X8000-MT, but they are different boards, the card is only supported via insmod option: options cx88xx card=91 For the record this is the eeprom dump, useful if someone wanted to implement the card auto detection: 07 ff ff ff f1 14 52 88 04 04 32 55 f8 00 a2 02 a1 00 40 63 06 11 44 30 03 df 40 80 00 20 00 73 3c 10 00 00 00 00 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff a0 00 Signed-off-by:

div_u64() does a 64-by-32 division, while the divisor max2175.xtal_freq is unsigned long, thus 64-bit on 64-bit platforms. Hence the proper function to call is div64_ul(). Note that this change does not have any functional impact, as the crystal frequency must be much lower than the 32-bit limit anyway. On 32-bit platforms, the generated code is the same. But at least on arm64, this saves an AND-instruction to truncate xtal_freq to 32-bit. Signed-off-by:

This includes a hack for the device as it returns only 0xff after a new firmware is loaded. To quote Mauro: "When the [...] firmware that came with the device is replaced by a new one, any I2C data received from the tuner will be replaced by 0xff. Probably, the vendor firmware has some patch specifically designed for this device. So, we can't replace by the generic firmware. The right solution would be to extract the [...] firmware from the original driver and ask the driver to load the specifically designed firmware, but, while we don't have that, the next best solution is to just keep the original firmware at the device."

The CEC_MSG_GIVE_DECK_STATUS and CEC_MSG_GIVE_TUNER_DEVICE_STATUS commands both have a status_req argument: ON, OFF, ONCE. If ON or ONCE, then the follower will reply with a STATUS message. Either once or whenever the status changes (status_req == ON). If status_req == OFF, then it will stop sending continuous status updates, but the follower will *not* send a STATUS message in that case. This means that if status_req == OFF, then msg->reply should be 0 as well since no reply is expected in that case. Signed-off-by:

This demod implements an i2c adapter for attached tuner and relays i2c messages from users (dvb adapters / bridge chips). Some of them, such as Friio dvb card using gl861, require each pair of i2c messages for one read to be issued as two separate transactions. This patch adds a configuration option to enable this split. Signed-off-by:

For Friio dvb cards, a distinct I2C algo was provided to support some "long" I2C messages used in relaying tuner I2C via demod. Since the other (generic) i2c algo in this module has been patched to support those messages in a more generic way, this patch replaces and integrates the device-specific i2c algo with the generic one and simplifies the code.
