There is only one 'if' statement changed by the patch.  Apart from that 
(and the typos in the patch description), the patch is fine as far as it 
goes.  However, the checkpatch script identifies several similar 
"unnecessary parentheses" issues in this file, and it would be better to 
take care of them all with a single patch rather than patching them one 
at a time.

Ick, no, now I need to remember which has higher precedence, "&" or
"&&".  It's "&" right?  I should not have to go look it up.

The code as-is is just fine.
