>From 5bb77b58d81591963c8bd6754276c1a78d80c4a4 Mon Sep 17 00:00:00 2001 From: Sakthivel K <Sakthivel.SaravananKamalRaju@xxxxxxxx> Date: Mon, 11 Mar 2013 20:38:50 +0530 Subject: [PATCH V2 08/12] pm80xx: Firmware flash memory free fix, with addition of new memory region for it Performing pci_free_consistent in tasklet had result in a core dump. So allocated a new memory region for it. Fix for passing proper address and operation in firmware flash update.
