Subject: [PATCH V5 14/31] smartpqi: remove timeouts from internal cmds
Date: Thu, 11 Mar 2021 14:16:14 -0600	[thread overview]
Message-ID: <161549377451.25025.12306492868851801623.stgit@brunhilda> (raw)
In-Reply-To: <161549045434.25025.17473629602756431540.stgit@brunhilda>

From: Kevin Barnett <kevin.barnett@microchip.com>

Remove timeouts for driver initiated commands.
 * Responses to internal requests can take longer
   than hard coded timeout values and the driver
   will still have an outstanding request that may
   complete in the future with no context.
