2a0d056015 V4L/DVB (13081): saa7134: use the #define for the xc5000 radio_input field
Dmitri's patch for the Behold X7 didn't use the #define I had setup for
XC5000_RADIO_FM1, so cut over to using that instead of "1".

ec994d0505 V4L/DVB (13078): em28xx: fix support for Terratec Cinergy T XS (005e)
Make analog audio, dvb and the remote work on a Terratec Cinergy Hybrid
XS (em2882).

Note by djh: Thanks go out fo Andrej Suligoi for his contribution in providing
and testing pretty much the exact same patch as provided by Uros.  Between
the two of them, they got all the core functionality working for the device.

f91cb65b94 V4L/DVB (13077): em28xx: Add support for new variant of KWorld 2800d
Seems that the reference design used for the KWorld 2800d switched from the
em2860 to em2862, so we need to add the new USB id (and the i2c hash remains
so all we need is the default em2862 id.

Thanks to Ian Young for reporting the issue and testing the fix.

75757507e0 DMI: allow omitting ident strings in DMI tables
The purpose of dmi->ident is twofold - it may be used by DMI callback
functions when composing log messages; it is also used to determine
end of DMI table in dmi_check_system() and dmi_first_match(). However,
in case when callbacks are not interested in using ident at all it just
wastes memory. Let's make entries with empty first match slot serve as
end-of-table markers instead.

5d990b6275 PCI: add pci_request_acs
Commit ae21ee65e8 "PCI: acs p2p upsteram
forwarding enabling" doesn't actually enable ACS.

Add a function to pci core to allow an IOMMU to request that ACS
be enabled.  The existing mechanism of using iommu_found() in the pci
core to know when ACS should be enabled doesn't actually work due to
initialization order;  iommu has only been detected not initialized.

Have Intel and AMD IOMMUs request ACS, and Xen does as well during early
init of dom0.

b26a34aa47 PCI: fix BUG_ON triggered by logical PCIe root port removal
This problem happened when removing PCIe root port using PCI logical
hotplug operation.

The immediate cause of this problem is that the pointer to invalid
data structure is passed to pcie_update_aspm_capable() by
pcie_aspm_exit_link_state(). When pcie_aspm_exit_link_state() received
a pointer to root port link, it unconfigures the root port link and
frees its data structure at first. At this point, there are not links
to configure under the root port and the data structure for root port
link is already freed. So pcie_aspm_exit_link_state() must not call
pcie_update_aspm_capable() and pcie_config_aspm_path().

This patch fixes the problem by changing pcie_aspm_exit_link_state()
not to call pcie_update_aspm_capable() and pcie_config_aspm_path() if
the specified link is root port link.
