Pull TDA998x i2c driver fixes from Russell King:
 "This fixes the double-checksumming of the AVI infoframe which was
  resulting in the checksum always being zero.  It went unnoticed as
  none of my HDMI devices had a problem with this"

[ Pulling directly from rmk since Dave Airlie is on vacation  - Linus ]
