Subject: [PATCH] usb: gadget: tegra-xudc: Constify static structs
Date: Thu, 13 May 2021 22:09:08 +0200	[thread overview]
Message-ID: <20210513200908.448351-1-rikard.falkeborn@gmail.com> (raw)

Constify a couple of ops-structs that are never modified, to let the
compiler put them in read-only memory.
