The USB buffer may be used for DMA and there may be a caching problem if the buffer is part of the device structure. Thanks to Alan Stern. Signed-off-by:

Not a bug as such, but it looks really strange doing this before checking whether the state structure could be allocated. Signed-off-by:

cx18: Simplify queue flush logic to prevent oops in cx18_flush_queues(). If accounting of a queue is in error, logic borrowed from ivtv will cause an oops when flushing the queues for a stream. This change greatly simplifies the queue flush logic, and sets the queue back to sane defaults on a flush. Signed-off-by:

This patch fixes several small issues at vivi register routines: 1) minor and n_devs should be unsigned; 2) n_devs = 0 were not properly handled; 3) if n_devs specify a high number, the driver would just roll back and won't register any device. The proper behaviour is to keep all succeded devices registered; 4) both n_devs and minor were using 0 as permissions. Better to have them with 0444. With the current patch, if n_devs specify a very large value, it will register all possible devices. For example, on a machine without any other V4L drivers loaded, with this patch, we will have something like: vivi: V4L2 device registered as /dev/video0 vivi: V4L2 device registered as /dev/video1 vivi: V4L2 device registered as /dev/video2 ... vivi: V4L2 device registered as /dev/video31 video_register_device_index: get_index failed Video Technology Magazine Virtual Video Capture Board ver 0.5.0 successfully loaded. 5) The number of allocated devices on success is now kept at n_devs: $ cat /sys/module/vivi/parameters/n_devs 32 Thanks to Henne <henne@nachtwindheim.de> for pointing that there were some issues at vivi.

The old Mediavision Pro Movie Studio legacy ISA V4L1 driver was found to hang the boot during Ingo Molnar's testing of randconfig kernels. Have it require a "pms.enable=1" kernel parameter to enable the driver when builtin which avoids such problems. This is a deprecated and, very likely, unused driver. Nothing changes modular behaviour moreover. Signed-off-by:

If saa7134_init is run before v4l2_i2c_drv_init (tuner), then saa7134_board_init2 will try to set the tuner type for devices that don't exist yet. This moves tuner to before all of the device-specific drivers so that it's loaded early enough on boot. Signed-off-by:

This patch adds a V4L2_CAP_SENSOR_UPSIDE_DOWN flag to the capabilities flags, and sets this flag for the Philips SPC200NC cam (which has its sensor installed upside down). The same flag is also needed and added for the Philips SPC300NC. Together with a patch to libv4l which adds flipping the image in software this fixes the upside down display with the SPC200NC cam.
