[PATCH] I2C: Move hwmon drivers (2/3)
Part 2: Move the driver files themselves. Note that the patch "adds trailing whitespace", because it does move the files as-is, and some files happen to have trailing whitespace. From: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
