hwmon: (f71805f) Fix checkpatch issues

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: need consistent spacing around '|' (ctx:VxW)
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead
WARNING: static const char * array should probably be static const char * const

Also modified multi-line comments to follow Documents/Codingstyle.
