Subject: checkpatch: return is not a function -- parentheses for casts are ok too
X-Git-Tag: v2.6.27-rc1~717
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=fee61c47d15270bdea699a8a3dd867f0825c3541;p=linux-2.6-omap-h63xx.git

checkpatch: return is not a function -- parentheses for casts are ok too

Casts require parentheses so it is possible to have something like this:

	return (int)(*a);

This miss trips the complexity function.  Ensure that the two separate
parenthesised sections are not coelesced.
