Subject: [PATCH 2/5] lib/crc: remove unnecessary prompt for CONFIG_CRC7
Date: Tue,  4 Mar 2025 15:07:09 -0800	[thread overview]
Message-ID: <20250304230712.167600-3-ebiggers@kernel.org> (raw)
In-Reply-To: <20250304230712.167600-1-ebiggers@kernel.org>

From: Eric Biggers <ebiggers@google.com>

All modules that need CONFIG_CRC7 already select it, so there is no need
to bother users about the option.
