hwmon: (w83627hf) Fix checkpatch issues
Fixed: WARNING: simple_strtol is obsolete, use kstrtol instead WARNING: simple_strtoul is obsolete, use kstrtoul instead ERROR: do not use assignment in if condition Modify multi-line comments to follow Documentation/CodingStyle. Other checkpatch issues not fixed to reduce number of conflicts with pending rewrite as mfd driver. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
