The only time checkpatch should bleat any message
is when there is a return; statement indented with
a single tab.
This form should be fine and not generate any
checkpatch warning.
void function(void)
{
...
if (err)
return;
...
}
If you want to use exit labels, I suggest you
use this form:
void function(void)
{
...
if (err)
goto exit;
...
exit:
;
}
