The driver includes an internal table specifying additional information on a per device-type basis. This works great until somebody tries to run-time associate another USB ID with the driver. This change should hopefully allow the driver to fail gracefully under such a circumstance. Signed-off-by:

The earlier change from Hans Verkuil that pushed the BKL from video_open() down into the drivers should be unneeded for the pvrusb2 driver. This driver's implementation for open already protects its internal structures through other means, thus the BKL is not required. This change reverses Hans' previous change, for the pvrusb2 driver. It probably would have been a good idea for Hans to previously have asked for my ack before committing his change. Signed-off-by:

Add support for the 'full-ts' hardware modification. On full-featured cards the data throughput is limited by the hardware design. The full-ts mod removes this bottleneck, i.e. the card is able to deliver the complete transport stream of a transponder.

When the input is set to tuner and no antenna is connected, the BT848 can flood VPRES interrupts. So we don't want to enable this type of interrupts when the input it set to tuner. As we don't do anything when receiving such an interrupt anyway, the easiest fix is to simply not unmask this specific interrupt. Signed-off-by:

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:

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:
