Subject: [PATCH] crypto: eip93: Make read-only arrays static const
Date: Wed,  2 Apr 2025 12:13:47 +0100	[thread overview]
Message-ID: <20250402111347.409795-1-colin.i.king@gmail.com> (raw)

Don't populate the read-only arrays sha256_init, sha224_init, sha1_init
and md5_init on the stack at run time, instead make them static.
