While new PEAK_PCIE_OEM_ID has been defined since 3.17, no corresponding
entry has been added in the peak_pci_tbl[] of the peak_pci CAN driver.
This patch enables now users of the PCAN-PCI Express OEM card to run the
peak_pci driver too.

Add PCI ID definition for the single channel PCAN ExpressCard 34 adapter. Due
to the subsystem id evaluation the correct number of channels (here 1) is
created at initialization time. Tested including the LED functionality.

We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
meet kernel coding style guidelines. This issue was reported by checkpatch.
A simplified version of the semantic patch that makes this change is as
follows (http://coccinelle.lip6.fr/):
// <smpl>
@@
identifier i;
declarer name DEFINE_PCI_DEVICE_TABLE;
initializer z;
@@
- DEFINE_PCI_DEVICE_TABLE(i)
+ const struct pci_device_id i[]
= z;

As remarked by Christopher R. Baker in his post at
http://marc.info/?l=linux-can&m=139707295706465&w=2
there's a possibility for an use after free condition at device removal.
This simplified patch introduces an additional variable to prevent the issue.
Thanks for catching this.

My objective is to be able to totally discriminate CAN ports on multi-port
cards via udev so as to rename them to semantically interesting/unique names
for my system (e.g., "ecuCAN" and "auxCAN" instead of "can0" and "can1").
The following patch assigns the dev_id field to match the channel number on all
multi-channel devices. I can only test my two-port Peak PCI card, but it works
as expected: ATTRS{dev_id} now expresses the port number and my udev rules now
unambiguously pick out and rename my individual CAN ports.

That patch fixed a define conflict between the SH architecture and the sja1000

the prefix of the SJA1000 controller registers from "REG_" to "SJA1000_".

Pull networking update from David Miller:
1) Checkpoint/restarted TCP sockets now can properly propagate the TCP
timestamp offset. From Andrey Vagin.
2) VMWARE VM VSOCK layer, from Andy King.
3) Much improved support for virtual functions and SR-IOV in bnx2x,
from Ariel ELior.
4) All protocols on ipv4 and ipv6 are now network namespace aware, and
all the compatability checks for initial-namespace-only protocols is
removed. Thanks to Tom Parkin for helping deal with the last major
holdout, L2TP.
5) IPV6 support in netpoll and network namespace support in pktgen,
from Cong Wang.
6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration
Protocol (MVRP) support, from David Ward.
7) Compute packet lengths more accurately in the packet scheduler, from
Eric Dumazet.
8) Use per-task page fragment allocator in skb_append_datato_frags(),
also from Eric Dumazet.
9) Add support for connection tracking labels in netfilter, from
Florian Westphal.
10) Fix default multicast group joining on ipv6, and add anti-spoofing
checks to 6to4 and 6rd. From Hannes Frederic Sowa.
11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern
times, rearrange inet frag datastructures for better cacheline
locality, and move more operations outside of locking. From Jesper
Dangaard Brouer.
12) Instead of strict master <--> slave relationships, allow arbitrary
scenerios with "upper device lists". From Jiri Pirko.
13) Improve rate limiting accuracy in TBF and act_police, also from Jiri
Pirko.
14) Add a BPF filter netfilter match target, from Willem de Bruijn.
15) Orphan and delete a bunch of pre-historic networking drivers from
Paul Gortmaker.
16) Add TSO support for GRE tunnels, from Pravin B SHelar. Although
this still needs some minor bug fixing before it's %100 correct in
all cases.
17) Handle unresolved IPSEC states like ARP, with a resolution packet
queue. From Steffen Klassert.
18) Remove TCP Appropriate Byte Count support (ABC), from Stephen
Hemminger. This was long overdue.
19) Support SO_REUSEPORT, from Tom Herbert.
20) Allow locking a socket BPF filter, so that it cannot change after a
process drops capabilities.
21) Add VLAN filtering to bridge, from Vlad Yasevich.
22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in
the ipv6 routes, from YOSHIFUJI Hideaki.

This patch adds the support for 4 new PCI boards based on the SJA1000 CAN
controller, from PEAK-System Technik:
. PCAN-miniPCIe (PCI-Express Mini slots, available as single or dual-channel)
. PCAN-cPCI (CompactPCI format, available as single or dual-channel)
. PCAN-PC/104-Plus (PC/104-Plus system, av. as 1, 2 or 4 channels)
. PCAN-PCI/104-Express (PCI/104-Express system, av. as 1 or 2 channels)
This patch also fixes a typo in existing "PEAK_MPCI_DEVICE_ID" identifier
(missing "e" for Express). Finally, it also changes the author as well as it
updates the module supported devices list.
