From 2b053729a84b6aac197df51b8729bc9fec743bff Mon Sep 17 00:00:00 2001 From: "Salyzyn, Mark" <mark_salyzyn@adaptec.com> Date: Thu, 2 Aug 2007 15:38:59 -0400 Subject: [PATCH] [SCSI] aacraid: prevent panic on adapter resource failure If the driver fails to allocate the contiguous (DMAable) memory for system reasons, we fail to load the instance, but then we try to free the <nul> allocation in the cleanup code and we get a panic in pci_free_consistent(). This is reported against an older kernel, hope this is relevant for latest/greatest.
