Subject: [PATCH][next] dmaengine: amd: qdma: make read-only arrays h2c_types and c2h_types static const
Date: Thu, 12 Sep 2024 14:10:17 +0100	[thread overview]
Message-ID: <20240912131017.588141-1-colin.i.king@gmail.com> (raw)

Don't populate the read-only arrays h2c_types and c2h_types on the
stack at run time, instead make them static const.
