Subject: [PATCH] thunderbolt: Constify static attribute_group structs
Date:   Sat,  9 Jan 2021 00:09:19 +0100
Message-Id: <20210108230918.32302-1-rikard.falkeborn@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The only usage of these is to put their addresses in arrays of pointers
to const attribute_groups. Make them const to allow the compiler to put
them in read-only memory.
