- pnp-dont-sort-by-type-in-sys-resources.patch removed from -mm tree

[akpm@linux-foundation.org]

The patch titled
     pnp: dont sort by type in /sys/.../resources
has been removed from the -mm tree.  Its filename was
     pnp-dont-sort-by-type-in-sys-resources.patch

This patch was dropped because it was merged into mainline or a subsystem tree

The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: pnp: dont sort by type in /sys/.../resources
From: Bjorn Helgaas <bjorn.helgaas@hp.com>

Rather than stepping through all IO resources, then stepping through
all MMIO resources, etc., we can just iterate over the resource list
once directly.

This can change the order in /sys, e.g.,

    # cat /sys/devices/pnp0/00:07/resources     # OLD
    state = active
    io 0x3f8-0x3ff
    irq 4

    # cat /sys/devices/pnp0/00:07/resources     # NEW
    state = active
    irq 4
    io 0x3f8-0x3ff

The old code artificially sorted resources by type; the new code
just lists them in the order we read them from the ISAPNP hardware
or the BIOS.
