[UPDATED] [GIT FIXES for 2.6.38] Fix cx23885 and cx25840 regressions, fix ivtv DMA error handling, and add new cx18 board profile.

[Andy Walls <awalls@md.metrocast.net>]

Mauro,

Please pull the following fixes for 2.6.38.  This is a resend of my
original pull request with two additional patches.

Thanks go to Sven Barth for reporting the regression with the CX2583x
chips in cx25840 and providing a patch.

Thanks also go to Mark Zimmerman for climing the git learning curve and
devoting the time perform a git bisect to isolate the cx23885
regression.

Thanks go to Michael for perform some excellent reasoning and working up
a patch to correct a long standing problem with the way the ivtv driver
deals with certain DMA Errors.  Thanks also go to Pete for testing
Mike's patch.  (I have altered Michael's original patch slightly, to
clear status errors only when it should be safe to do so without hanging
the DMA engine.)

Thanks to Devin and Hauppauge for adding a new board profile for the
latest HVR-1600 designs having a different DTV tuner and demodulator.

I think that's everyone...

Regards,
Andy
