Replace the old register_chrdev with the more flexible register_chrdev_region. Ensure that the release() is called when the very last chardev usage was released, and not when the sysfs devices were removed. This should simplify hotpluggable drivers considerably. Tested-by:

Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches. Signed-off-by:

This patch is on behalf of Stephen Backway <stev391@email.com>, and represents two patches I received (and some subsequent whitespace cleanup I had due to how I pulled the patches). From the original author: a) Add DVB support for the Leadtek Winfast PxDVR3200 H. b) The tuner callback previously checked the command 3 times: 1) To see if it was the XC2028_RESET_CLK 2) To see if it was not the XC2028_RESET_TUNER 3) To see if it was the XC2028_RESET_TUNER This patch removes the third check.

A simple state machine was added to saa7134_ts. It has three states: SAA7134_TS_STOPPED SAA7134_TS_BUFF_DONE SAA7134_TS_STARTED When buffer_setup is run we start the TS initialization: set SAA7134_TS_STOPPED. When all buffers are prepared we write data into DMA register and set SAA7134_TS_BUFF_DONE. When the first buffer is active start TS and set SAA7134_TS_STARTED. When ts_release is called stop TS and set SAA7134_TS_STOPPED. Signed-off-by:Beholder Intl. Ltd. Dmitry Belimov <d.belimov@gmail.com> Signed-off-by:

The driver_data field of the device structure was zeroed, thus losing this information. Many drivers set this up before calling video_device_register, so we have to ensure that it isn't lost. Signed-off-by:

Add a second release function: video_device_release_empty It can be used by drivers that have statically allocated video_device structs. Its use usually, but not always, indicates laziness on the part of the driver programmer. Signed-off-by:

cx18: Have CX23418 release buffers at end of capture. The CX23418 reuses task handles so we need to have it release the buffers associated with a task handle at the end of a capture. If we don't, buffer ids used for one type of stream in the driver (MPEG, TS, PCM), could be used for another type of stream by the CX23418, if a previously used handle is assigned to a different type of stream. The driver would drop valid buffers when this happened. Signed-off-by:

When a suspended device has been reset instead of being resumed, USB core calls the reset_resume method if available instead of unbinding and rebinding the device. This patch implements reset_resume by reusing the current resume implementation and simplifies the resume method by skipping the controls restore stage. Resuming from autosuspend should be faster.
