[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). Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
