hwmon: (smsc47m192) Fix checkpatch issues

Browse source 
Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
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)
NOTE: whitespace errors detected, you may wish to use scripts/cleanpatch or
WARNING: please, no space before tabs
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead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 fixed (false positive):
ERROR: Macros with multiple statements should be enclosed in a do - while loop
