[0/4] MaxLinear mxl692 demod-tuner / Hauppauge usb QuadHD

Attached is a new driver for MaxLinear mxl692 ATSC/QAM combo
tuner-demodulator. The driver is used by em28xx based
Hauppauge USB QuadHD.

The Hauppauge USB QuadHD contains four instances of the mxl692,
configured as two "dual tuner" em28xx devices.

Bus 003 Device 006: ID 2040:846d Hauppauge
Bus 003 Device 005: ID 2040:846d Hauppauge
Bus 003 Device 004: ID 04e2:0404 Exar Corp.

The ATSC portion works fully, the QAM portion needs some TLC,
and is therefore not listed in the DVB capabilities.

The driver is based off vendor provided GPLv2 source code.

I have left the few long line warnings as is, due to recent
developments/statements regarding this topic. I do not feel
the driver would be made any clearer by arbitrarily
splitting up the remaining lines further.

All endianess issues have been sorted out. The driver is verified
fully working on a (ancient) powerpc Mac Mini running current
mainline kernel.
