[PATCH] I2C: Coding style cleanups to via686a

The via686a hardware monitoring driver has infamous coding style at the
moment. I'd like to clean up the mess before I start working on other
changes to this driver. Is the following patch acceptable? No code
change, only coding style (indentation, alignments, trailing white
space, a few parentheses and a typo).
