Subject: [char-misc-next 1/2] mei: don't clean control queues on notify request timeout
Date: Wed, 20 Apr 2016 11:03:54 -0400 [thread overview]
Message-ID: <1461164635-8916-1-git-send-email-tomas.winkler@intel.com> (raw)
From: Alexander Usyskin <alexander.usyskin@intel.com>
Timeout on notify request is not a fatal condition, and actually
cleaning control queues will disrupt other control flows of the
same client.
