A new buffer for a packet is created when a icmp packet is received.
This happens in a context with disabled irq. Thus we are not allowed to
sleep or call function which might sleep. kmalloc must be called with
GFP_ATOMIC instead of GFP_KERNEL to ensure that it does not sleep.

Free_netdev is registered as destructor in interface_setup for every
soft_device. This destructor is automatically called from
unregister_netdev and we must not call it again for the freed
net_device.

We must call unregister_netdev when we couldn't initialise the
batman-adv module and the soft_device was registered. There are two
version of the function which we can use:
* unregister_netdevice - removes device
* unregister_netdev - takes rtnl semaphore and remove device
We don't hold the semaphore in an error situation. So we must use
unregister_netdev.

Qualcomm development of the MSM SOC framebuffer driver has
diverged significantly from the driver used by Android. This
is a snapshot of our current driver, in all it's agony. We are
putting this in staging to help with the process of converging
the two drivers.
At this point, the driver has been tested only in dumb
framebuffer mode.

For write(), any data copied to the data buffer after the previously
set up streaming acquisition command has finished won't be used, but a
non-empty write() does not currently return 0 (or -EPIPE on error) after
the command has finished until the data buffer has been filled up.
Change this behavior to return 0 (or -EPIPE) any time after the command
has finished, without bothering to fill up the buffer with more useless
data.

Add support for the Advantech PCI-1735U card, including support for a

The counter subdevice needs more testing, as the only person I know who
tried it couldn't get it to work!

The Addi-Data PCI drivers for Comedi use sprintf() in their comedi
"attach" routine to construct a string to pass as the name in the call
to request_irq(). All calls to "attach" routine share the same static
buffer for this name, but the contents will differ on each call
(including the comedi device number and the comedi board name). This
changes the name displayed in /proc/interrupts for previous calls to
request_irq() using the same buffer. Just use the board name instead;
it has slightly less information (no comedi device number) but at least
it doesn't change over the lifetime of the IRQ handler.
