hwmon: (max6650) Fix checkpatch issues
Fixed: ERROR: do not use assignment in if condition ERROR: open brace '{' following struct go on the same line ERROR: spaces required around that '||' (ctx:VxV) ERROR: switch and case should be at the same indent WARNING: simple_strtoul is obsolete, use kstrtoul instead Cc: Hans J. Koch <hjk@hansjkoch.de> Acked-by: Hans J. Koch <hjk@hansjkoch.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
