Subject: [PATCH 1/6] tty: con3215: drop raw3215_info::ubuffer
Date: Tue, 21 Nov 2023 11:36:21 +0100	[thread overview]
Message-ID: <20231121103626.17772-2-jirislaby@kernel.org> (raw)
In-Reply-To: <20231121103626.17772-1-jirislaby@kernel.org>

clang-struct [1] found raw3215_info::ubuffer unused.

It's actually not used since 2004 when we switched to kernel buffers.
