Subject: [PATCH] Bluetooth: make array bt_uuid_any static const
Date: Mon, 14 Feb 2022 21:51:30 +0000 [thread overview]
Message-ID: <20220214215130.66993-1-colin.i.king@gmail.com> (raw)
Don't populate the read-only array bt_uuid_any on the stack but
instead make it static const. Also makes the object code a little
smaller.
