Hi,
The new sysfs-backingstore patches cause an oops when I ifup a prism54 based device, heres the dmesg section:
Loaded prism54 driver, version 1.2 PCI: Enabling device 0000:03:00.0 (0000 -> 0002) ACPI: PCI interrupt 0000:03:00.0[A] -> GSI 9 (level, low) -> IRQ 9 eth0: no IPv6 routers present eth2: islpci_open() eth2: resetting device... eth2: uploading firmware...

Backing out all sysfs-backing-store patches cures the problem. (sysfs-backing-store-prepare-file_perations.patch alone triggers the oops)
I think the oops comes from drivers/base/firmware_class.c:423
