[PATCH nf-next v4 02/10] netfilter: bitwise: remove NULL comparisons from attribute checks.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In later patches, we will be adding more checks.  In order to be
consistent and prevent complaints from checkpatch.pl, replace the
existing comparisons with NULL with logical NOT operators.
