Subject: [PATCH AUTOSEL 6.12 27/36] scsi: mpi3mr: Start controller indexing from 0

From: Ranjan Kumar <ranjan.kumar@...adcom.com>

[ Upstream commit 0d32014f1e3e7a7adf1583c45387f26b9bb3a49d ]

Instead of displaying the controller index starting from '1' make the
driver display the controller index starting from '0'.
