Subject: [PATCH 02/28] char: remove the SGI tiocx/mbcs driver
Date: Tue, 13 Aug 2019 09:24:48 +0200
Message-ID: <20190813072514.23299-3-hch@lst.de> (raw)
In-Reply-To: <20190813072514.23299-1-hch@lst.de>

The SGI SN2 support is about to be removed.  Remove this driver that
depends on the SN2 support.
