Hello Ben,

a few weeks ago Zoran Stojsavljevic reported a problem with the RTC
on the iwg20d that turned out to be a problem with the I2C driver
sporadically sending data twice. This series backports the commits
from Wolfram that make up for the fix.

This series applies on top of v4.4.126-cip22.

Thanks,
Fabrizio
