[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.
