Subject: [PATCH][next] usb: r8a66597-hcd: make read-only const arrays static
Date: Thu, 12 Sep 2024 14:23:45 +0100 [thread overview]
Message-ID: <20240912132345.589397-1-colin.i.king@gmail.com> (raw)
Don't populate the read-only const arrays fifoaddr, fifosel and fifoctr
on the stack at run time, instead make them static.
