return bar;
- **UNNECESSARY_INT**
- int used after short, long and long long is unnecessary. So remove it.
-
- **UNSPECIFIED_INT**
- Kernel style prefers "unsigned int <foo>" over "unsigned <foo>" and
- "signed int <foo>" over "signed <foo>".

**TYPO_SPELLING**
Some words may have been misspelled. Consider reviewing them.
-
- **UNNECESSARY_ELSE**
- Using an else statement just after a return or a break statement is
- unnecassary. For example::
-
- for (i = 0; i < 100; i++) {
- int foo = bar();
- if (foo < 1)
- break;
- else
- usleep(1);
- }
-
- is generally better written as::
-
- for (i = 0; i < 100; i++) {
- int foo = bar();
- if (foo < 1)
- break;
- usleep(1);
- }
-
- So remove the else statement. But suppose if a if-else statement each
- with a single return statement, like::
-
- if (foo)
- return bar;
- else
- return baz;
-
- then by removing the else statement::
-
- if (foo)
- return bar;
- return baz;
-
- their is no significant increase in the readability and one can argue
- that the first form is more readable because of indentation, so for
- such cases do not convert the existing code from first form to second
- form or vice-versa.
