From 87c32dbd7eff10681aa09226be887a222245883f Mon Sep 17 00:00:00 2001 From: James Smart Date: Mon, 10 Sep 2018 10:30:47 -0700 Subject: [PATCH] scsi: lpfc: Correct invalid EQ doorbell write on if_type=6 [ Upstream commit aad59d5d34738d6fd8c359df8048a84cd443e504 ] During attachment, the driver writes the EQ doorbell to disable potential interrupts from an EQ. The current EQ doorbell format used for clearing the interrupt is incorrect and uses an if_type=2 format, making the operation act on the wrong EQ. Correct the code to use the proper if_type=6 EQ doorbell format. Signed-off-by: Dick Kennedy Signed-off-by: James Smart Signed-off-by: Martin K.
