**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>".

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.
