if (priv->i2c_props.adap == NULL) then exit any function that would send commands over the i2c bus. We allow drivers to attach without an i2c adapter for cases where the dvb demod accesses the tuner directly via calc_regs. Signed-off-by:

Convert tda9887 to use the new hybrid_tuner_request_state and hybrid_tuner_release_state macros to manage state sharing between hybrid tuner instances. Some ATSC/DVB cards need to put the analog demodulator into standby before tuning digital. This patch allows us to attach the tda9887 driver to the digital side of the bridge driver and be able to put it into standby without jeopardizing the analog demod driver's state. Signed-off-by:

There are two tuner types: those for M/N standards and those for all others. However, M/N standards are not always 60 Hz (PAL-N/Nc are 50 Hz), so rename the module option accordingly. Signed-off-by:

Previously, the macro DVR_FEED, which is used to recognize and filter out duplicate packets going to the DVR device, used the TS_PAYLOAD_ONLY flag to identify a packet's destination. This kind of filtering was introduced by the following two changesets: Now, that it is possible to record TS PIDs using the demux device by setting the output type to DMX_OUT_TSDEMUX_TAP, checking TS_PAYLOAD_ONLY is not sufficient anymore. Therefore another flag, TS_DEMUX, is added to specify the output type of a feed. This allows multiple clients to filter the same TS PID on a demux device simultaneously. Signed-off-by:

The pvrusb2 driver normally picks up the default video standard from the eeprom on Hauppauge devices, but the OnAir HDTV and OnAir Creator are not Hauppauge devices, and do not store this information in any eeprom. These devices support NTSC/ATSC, so we should use NTSC by default when in analog mode. Signed-off-by:

This change significantly rearranges pvr2_context level initialization and operation: 1. A new kernel thread is set up for management of the context. 2. Destruction of the pvr2_context instance is moved into the kernel thread. No other context is able to remove the instance; doing this simplifies lock handling. 3. The callback into pvrusb2-main, which is used to trigger initialization of each interface, is now issued from this kernel thread. Previously it had been indirectly issued out of the work queue thread in pvr2_hdw, which led to deadlock issues if the interface needed to change a control setting (which in turn requires dispatch of another work queue entry). 4. Callbacks into the interfaces (via the pvr2_channel structure) are now issued strictly from this thread. The net result of this is that such callback functions can now also safely operate driver controls without deadlocking the work queue. (At the moment this is not actually a problem, but I'm anticipating issues with this in the future). 5. There is no longer any need for anyone to enter / exit the pvr2_context structure. Implementation of the kernel thread here allows this all to be internal now, simplifying other logic. 6. A very very longstanding issue involving a mutex deadlock between the pvrusb2 driver and v4l should now be solved. The deadlock involved the pvr2_context mutex and a globals-protecting mutex in v4l. During initialization the driver would take the pvr2_context mutex first then the v4l2 interface would register with v4l and implicitly take the v4l mutex. Later when v4l would call back into the driver, the two mutexes could possibly be taken in the opposite order, a situation that can lead to deadlock. In practice this really wasn't an issue unless a v4l app tried to start VERY early after the driver appeared. However it still needed to be solved, and with the use of the kernel thread relieving need for pvr2_context mutex, the problem should be finally solved. Signed-off-by:

The pvrusb2 tear-down logic was clearing two timers before stopping its internal work queue. That left a tiny window open where the work queue might run after the timers are stopped, possibly starting them again. This could lead to dangling pointers and an oops. Solution: Kill the work queue first, then delete the timers. Signed-off-by:

There is a callback that is issued to into pvr2_context from pvr2_hdw after initialization is done. There was a probability that this callback could get missed. Fixed. Signed-off-by:

Buffer size for printing pvrusb2 video standard strings was too small before. This is cosmetic; the printing logic is not able to overrun a too-short buffer. Signed-off-by:

The pvrusb2 driver dynamically generates an enumeration of support video standard combinations based on which video standard bits are set. ATSC modes don't fall into this since they are by nature not analog. The pvrusb2 driver has been warning about an inability to classify ATSC standards. This change causes the classification algorithm to ignore any ATSC standards (such things are better handled elsewhere anyway). Signed-off-by:

The pvrusb2 driver has used hardcoded logic to control the LED on the device. However this is really Hauppauge-specific behavior. This change defines a new device attribute for LED control and sets things up appropriately for Hauppauge devices. Signed-off-by:
