Convert code away from ->read_proc/->write_proc interfaces. Switch to

Most of the irq_req_t typedef'd struct can be re-worked quite
easily:
(1) IRQInfo2 was unused in any case, so drop it.
(2) IRQInfo1 was used write-only, so drop it.
(3) Instance (private data to be passed to the IRQ handler):
Most PCMCIA drivers using pcmcia_request_irq() to actually
register an IRQ handler set the "dev_id" to the same pointer
as the "priv" pointer in struct pcmcia_device. Modify the two
exceptions (ipwireless, ibmtr_cs) to also work this waym and
set the IRQ handler's "dev_id" to p_dev->priv unconditionally.
(4) Handler is to be of type irq_handler_t.
(5) Handler != NULL already tells whether an IRQ handler is present.
Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
irq_req_t.Attributes.

The CAPI interface incorrectly assumed that CAPI messages would always

The tty_operation chars_in_buffer() is not allowed to return a negative
value to signal an error. Corrects the problem flagged by commit
23198fda71, "tty: fix chars_in_buffers".

The size of receive buffer pointer was used to get size of
receive buffer instead of recvbuf_size itself, so only 4/8
bytes could be transfered.
This is a regression to 2.6.30 introduced by commit 8c90e11e35

Fix IOFUNC_MEMIO macro. WriteFiFo##name##_MIO use the wrong struct name,
this was missed because the macro was only called with this name.
Clarify with _func that the defined types are functions.
Add names to the parameters for better understanding the purpose.

In the PCI probe function struct pci_device_id points to the matched
entry of the ID table, but for devices which are matched with
PCI_ANY_ID sub IDs we want display the IDs of the device itself.

These changes were a direct result of using a semantic patch

The result of container_of should not be NULL. In particular, in this case
the argument to the enclosing function has passed though INIT_WORK, which
dereferences it, implying that its container cannot be NULL.
A simplified version of the semantic patch that makes this change is as
follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@
identifier fn,work,x,fld;
type T;
expression E1,E2;
statement S;
@@
static fn(struct work_struct *work) {
... when != work = E1
x = container_of(work,T,fld)
... when != x = E2
- if (x == NULL) S
...
}

Add support for cards based on the Tiger 300 and Tiger 320
ISDN PCI chip.
Currently only the ISAC ISDN line interface is supported.

This driver supports cards with Infineon ISAC/HSCX, ISACX, IPAC
and IPACX chips from various manufacturers.

Normally HDLC packets contain more as one byte (e.g a X25/X75 header).
But if you use plain HDLC framing, the current code do not encode
1 byte payloads, this patch fix that.

The original isdnhdlc code was developed for devices which had
reversed bitorder in the byte stream. Adding code to handle normal
bitstreams as well.

isdnhdlc is useful for other ISDN drivers as well.
Move the include file to a central location and the source
to the central isdn location.
