hwmon: (via686a) Fix checkpatch issues
Fixed:
ERROR: do not use assignment in if condition
ERROR: open brace '{' following function declarations go on the next line
ERROR: space prohibited before that close parenthesis ')'
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: that open brace { should be on the previous 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WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead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 fixed (false positive):
ERROR: Macros with multiple statements should be enclosed in a do - while loop
