Subject: [PATCH] pktcdvd: Correctly set rq->cmd_len in pkt_generic_packet()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=cef289633a9321cd99dd5f6cc935657dc487e9f0;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] pktcdvd: Correctly set rq->cmd_len in pkt_generic_packet()

It looks like the code in pkt_generic_packet() worked by luck in the past, but
after commit 186d330e682210100c671355580a8592e4a21692 leaving rq->cmd_len
uninitialized doesn't work any more.
