Subject: [PATCH 7/9] mtip32xx: fix minor number
Date: Mon, 11 May 2015 15:55:26 -0700 [thread overview]
Message-ID: <5551335E.8090005@micron.com> (raw)
When a device is surprise removed and inserted, it is assigned a new minor
number because driver use multiples of 'instance' number. Modified to use the
multiples of 'index' for minor number.
