Subject: PCI: fix sparse warning about pci_bus_flags
From: Roland Dreier <rdreier@cisco.com>
Date: Thu, 30 Mar 2006 12:55:10 -0800
Message-ID: <adamzf71wlt.fsf@cisco.com>

Sparse warns about casting to a __bitwise type.  However, it's correct
to do when defining the enum for pci_bus_flags_t, so add a __force to
quiet the warnings.  This will fix getting

    include/linux/pci.h:100:26: warning: cast to restricted type

from sparse all over the build.
