From b83d543fd934d565fb243ef348b06a61d794b31d Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Wed, 23 May 2012 20:40:54 -0500 Subject: [PATCH] [SCSI] be2iscsi: fix dma free size mismatch regression This patch should go into 3.5 fixes. The bug was added in the patches for the 3.5 feature window. As you can see from the patch I made a mistake. During development I switched from passing a struct to the size of the struct, but left the sizeof. This results in us allocating 4 bytes (sizeof(int)) but then calling pci_free_consistent with the size of the struct.
