hwmon: (gl520sm) 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: spaces required around that ':' (ctx:VxV) ERROR: spaces required around that '?' (ctx:VxV) ERROR: trailing statements should be on next line WARNING: line over 80 characters WARNING: simple_strtol is obsolete, use kstrtol instead WARNING: simple_strtoul is obsolete, use kstrtoul instead Modify multi-line comments to follow Documentation/CodingStyle. Not always fixed (complexity): ERROR: do not use assignment in if condition Signed-off-by: Guenter Roeck <linux@roeck-us.net>hifive-unleashed-5.1
