Subject: [PATCH net-next] net: wan: z85230: drop unused async state
Date: Wed, 7 Apr 2021 12:48:56 +0200 [thread overview]
Message-ID: <20210407104856.1345-1-johan@kernel.org> (raw)
According to the changelog, asynchronous mode was dropped sometime
before v2.2. Let's get rid of the unused driver-specific async state as
well so that it doesn't show up when doing tree-wide tty work.
