Subject: net: mvpp2: Adjust a null pointer check in mvpp2_egress_enable()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=dbbb2f034b5a5c1da368e4ac7e85a4ee4922f57b;p=openwrt%2Fstaging%2Fblogic.git

net: mvpp2: Adjust a null pointer check in mvpp2_egress_enable()

The script "checkpatch.pl" pointed information out like the following.

Comparison to NULL could be written "txq->descs".

Thus fix the affected source code place.
