From 7dd21308b17e2b657d167adc7e20b41b7c6bbe5c Mon Sep 17 00:00:00 2001 From: Brian King Date: Wed, 14 Mar 2012 21:20:08 -0500 Subject: [SCSI] ipr: Remove unnecessary interrupt clearing on new adapters The latest ipr hardware no longer requires the driver to issue any MMIOs to clear the interrupt so remove this to optimize performance.
