Subject: [PATCH] crypto: crc32c - Remove more outdated usage information
Date: Sat, 14 Mar 2026 10:31:30 -0700	[thread overview]
Message-ID: <20260314173130.16683-1-ebiggers@kernel.org> (raw)

Remove information from the crypto/crc32c.c file comment that is no
longer applicable now that nearly all users of CRC-32C are simply using
the crc32c() library function instead.  This continues the cleanup from
commit 0ef6eb10f2e0 ("crypto: Clean up help text for CRYPTO_CRC32C").

Signed-off-by: Eric Biggers <ebiggers@kernel.org>

This patch is targeting crc-next.
