Roger Hardiman dd11af6637 Update to driver 2.15. 
Main change is the addition of the bktr_mem module.

This holds onto the bktr driver's contiguously allocated memory
when the bktr driver is unloaded and reloaded.

This has to be done because it is virtually impossible to get
contiguous memory once a system is running.

Also tidied up the use of SMBUS, added a new Hauppauge tuner type (0x2c)
and a new Flyvideo vendor ID.

*
* The scheme used for probing cards faces these problems:
* It is impossible to work out which type of tuner is actually fitted,
* (the driver cannot tell if the Tuner is PAL or NTSC, Temic or Philips)
* It is impossible to determine what audio-mux hardware is connected.
* It is impossible to determine if there is extra hardware connected to the
* GPIO pins (eg radio chips or MSP34xx reset logic)
*
* However some makes of card (eg Hauppauge) come with a configuration eeprom
* which tells us the make of the card. Most eeproms also tell us the
* tuner type and other features of the the cards.
*
* The current probe code works as follows
* A) If the card uses a Bt878/879:
* 1) Read the sub-system vendor id from the configuration EEPROM.
* Select the required tuner, audio mux arrangement and any other
* onboard features. If this fails, move to step B.
* B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
* 1) Look for I2C devices. If there are none fitted, it is an Intel or
* VideoLogic cards.
* 2) Look for a configuration EEPROM.
* 2a) If there is one at I2C address 0xa0 it may be
* a Hauppauge or an Osprey. Check the EEPROM contents to determine which
* one it is. For Hauppauge, select the tuner type and audio hardware.
* 2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
* We still have to guess on the tuner type.
*
* C) If we do not know the card type from (A) or (B), guess at the tuner
* type based on the I2C address of the tuner.
*
* D) After determining the Tuner Type, we probe the i2c bus for other
* devices at known locations, eg IR-Remote Control, MSP34xx and TDA
* stereo chips.
