hwmon: (w83781d) Fix checkpatch issues
Browse files Browse the repository at this point in the history 
Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: "foo* bar" should be "foo *bar"
ERROR: space prohibited after that open parenthesis '('
ERROR: space required after that ',' (ctx:VxV)
ERROR: spaces required around that '==' (ctx:VxV)
WARNING: line over 80 characters
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead
WARNING: space prohibited between function name and open parenthesis '('

Not fixed (false positive):
ERROR: Macros with multiple statements should be enclosed in a do - while loop
ERROR: Macros with complex values should be enclosed in parenthesis

Not all fixed (code complexity):
ERROR: do not use assignment in if condition
