Subject: [PATCH 1/3] ipmi: Reset response handler when failing to send the command
Date: Mon, 7 Sep 2020 18:25:35 +0200 [thread overview]
Message-ID: <1599495937-10654-1-git-send-email-markubo@amazon.com> (raw)
When failing to send a command we don't expect a response. Clear the
`null_user_handler` like is done in the success path.
