Subject: [PATCH 5/7] lib/crc: remove unnecessary prompt for CONFIG_CRC_ITU_T
Date: Tue,  1 Apr 2025 15:15:58 -0700	[thread overview]
Message-ID: <20250401221600.24878-6-ebiggers@kernel.org> (raw)
In-Reply-To: <20250401221600.24878-1-ebiggers@kernel.org>

From: Eric Biggers <ebiggers@google.com>

All modules that need CONFIG_CRC_ITU_T already select it, so there is no
need to bother users about the option.
