Subject: [PATCH net-next 3/3] net: qualcomm: rmnet: Remove redundant command check
Date: Mon, 14 May 2018 14:08:47 -0600	[thread overview]
Message-ID: <1526328527-20026-4-git-send-email-subashab@codeaurora.org> (raw)
In-Reply-To: <1526328527-20026-1-git-send-email-subashab@codeaurora.org>

The command packet size is already checked once in
rmnet_map_deaggregate() for the header, packet and trailer size, so
this additional check is not needed.
