[PATCH] I2C: W83792D driver 1/3

I would like to announce support for W83792D chip. This driver was developed
by Winbond Electronics Corp. I added sysfs attributes callbacks infrastructure
plus various code fixes and codingstyle cleanups. I would like to thank Winbond
for supporting free software.

This patch is against 2.6.13rc3 plus hwmon-class and hwmon-split.
Separate patch for documantation and hwmon class register will follow.
