Subject: [PATCH] [net/ipv6] Remove redundant null check in hbh_mt6
Date: Wed, 24 Jun 2020 22:46:04 -0400 [thread overview]
Message-ID: <20200625024605.2881-1-gaurav1086@gmail.com> (raw)
oh cannot be NULL since its already checked above after
assignment and is being dereferenced before. Remove the
redundant null check.
