Subject: [PATCH] misc: tifm: Remove VLA
Date:   Mon,  9 Apr 2018 14:07:32 -0700
Message-Id: <20180409210732.3919-1-labbott@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

There's an ongoing effort to remove VLAs[1] from the kernel to eventually
turn on -Wvla. The single VLA can either take a value of 2 or 4 so switch
to the upper bound.
