hwmon: (w83l786ng) Fix checkpatch issues

Browse source 
Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: space required after that ',' (ctx:VxV)
WARNING: braces {} are not necessary for single statement blocks
WARNING: please, no space before tabs
WARNING: please, no spaces at the start of a line
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead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 complex values should be enclosed in parenthesis
