Subject: ipc/mqueue.c: delete an unnecessary check before the macro call dev_kfree_skb()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=97b0b1ad58fab9f71b1a6bc056a09af6065ec3bc;p=openwrt%2Fstaging%2Fblogic.git

ipc/mqueue.c: delete an unnecessary check before the macro call dev_kfree_skb()

dev_kfree_skb() input parameter validation, thus the test around the call
is not needed.

This issue was detected by using the Coccinelle software.
