Subject: [PATCH] sgi-gru: simplify procfs code some more
Date: Mon, 07 Oct 2019 11:30:46 -0700 [thread overview]
Message-ID: <cce61906a5f7f42f5b2b8b947fc61357bcb56e71.camel@perches.com> (raw)
Use seq_puts and simple string output and not seq_printf with formats
and individual strings to reduce overall object size.
