Fix checkpath.pl warning:
line over 80 characters
Block comments use * on subsequent lines
Block comments use a trailing */ on a separate line
Statements should start on a tabstop
Comparisons should place the constant on the right side of the test
Changes in V2:
Remove extra space after /*
Align single line comment
Block comments starts with /* followed by comments on the next line
Changes in V3:
Fix trailing space
Fix checkpatch.pl warning for blank line after enum declaration
Move macro definition to the top of the file
Align macro definitions
