[SCSI] be2iscsi: Fixing the /proc/interrupts problem V3
Fix be2iscsi driver to use a separate pointer for each irq action->name field and avoid display corruption in /proc/interrupts. The be2iscsi driver was using a single static array in a function for the irq action->name field. This results in garbage output from /proc/interrupts The pointer for action->name is garbage and scribbles the output on the screen. This patch fixes the problem: 156: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 PCI-MSI-X beiscsi_msix_0017 This patch is based on Prarit's patch here: http://www.spinics.net/lists/linux-scsi/msg52325.html but I have fixed up the failure paths and removed redundant check for !i suggested by Eike.
