2011-05-20[media] zoran: Drop unused module parameters encoder and decoderJean Delvare
The ability to force the encoder or decoder chip was broken by commit 0ab6e1c38d80ab586e3a1ca9e71844131d9f51dc in February 2009. As nobody complained for over 2 years, I take it that these parameters were no longer used so we can simply drop them.

2011-03-22[media] v4l: Add a media_device pointer to the v4l2_device structureLaurent Pinchart
The pointer will later be used to register/unregister media entities when registering/unregistering a v4l2_subdev or a video_device. With the introduction of media devices, device drivers need to store a pointer to a driver-specific structure in the device's drvdata. v4l2_device can't claim ownership of the drvdata anymore. To maintain compatibility with drivers that rely on v4l2_device storing a pointer to itself in the device's drvdata, v4l2_device_register() will keep doing so if the drvdata is NULL.

This patch allows this device successfully to show video, at least from its composite input.

2010-10-21V4L/DVB: v4l2: add core serialization lockHans Verkuil
Drivers can optionally set a pointer to a mutex in struct video_device. The core will use that to lock before calling open, read, write, unlocked_ioctl, poll, mmap or release. Updated the documentation as well and ensure that v4l2-event knows about the lock: it will unlock it before doing a blocking wait on an event and relock it afterwards. Ensure that the 'video_is_registered' check is done when the lock is held: a typical disconnect will take the lock as well before unregistering the device nodes, so to prevent race conditions the video_is_registered check should also be done with the lock held.
