Subject: rtnetlink: unlock on error path in netlink_dump()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c63d6ea3060d9e10773e869b1112e3a0efbcf820;p=linux-beck.git

rtnetlink: unlock on error path in netlink_dump()

In c7ac8679bec939 "rtnetlink: Compute and store minimum ifinfo dump
size", we moved the allocation under the lock so we need to unlock
on error path.
