Subject: tcm_qla2xxx: print port name via %*phC
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3c9786e59515ed18153bfa4a36e0a2e762c0dc68;p=openwrt%2Fstaging%2Fblogic.git

tcm_qla2xxx: print port name via %*phC

Instead of pushing each byte via stack let's use custom specifier which allows
to print small buffers as a hex string.
