hwmon: (smsc47m1) Fix checkpatch issues
Fixed: ERROR: code indent should use tabs where possible ERROR: do not use assignment in if condition ERROR: space required after that ',' (ctx:VxV) ERROR: spaces required around that '<=' (ctx:VxV) ERROR: spaces required around that '==' (ctx:VxV) ERROR: spaces required around that '>=' (ctx:VxV) ERROR: trailing statements should be on next line ERROR: trailing whitespace WARNING: simple_strtol is obsolete, use kstrtol instead WARNING: static const char * array should probably be static const char * const Modify multi-line comments to follow Documentation/CodingStyle. Also: s/#define^I/#define / Not fixed (false positive): ERROR: Macros with multiple statements should be enclosed in a do - while loop Cc: Jean Delvare <khali@linux-fr.org> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
