[linux-dvb] dib0700 remote control support fixed

[petercarm]

I've been busy testing and I have an apology to make.

It looks like the problem is with a riser card.  When I moved the Nova-T
500 to an identical VIA SP8000 in a case that allowed a direct fitting
PCI card, the problems stabilized.

This does explain why I was the only one seeing these problems.  Curious
that the card was stable for DVB functions if the RC polling was
disabled.  I will amend the wiki to make sure it reflects the current
status of the driver.
