Subject: [TIPC]: Remove redundant NULL check when discarding buffers
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=11ecede7874efb9c31184b49090fc6d9bb17f9f6;p=openwrt%2Fstaging%2Fblogic.git

[TIPC]: Remove redundant NULL check when discarding buffers

This patch eliminates a null pointer check when discarding a
TIPC message buffer, since kfree_skb() already handles this
situation.

Acknowledgements to Florian Westphal (fw@strlen.de> for
suggesting this enhancement.
