Jiri Slaby 91905b6f4a parport: parport_pc, do not remove parent devices early
When the parport_pc module is removed from the system, all parport
devices are iterated in parport_pc_exit and removed by a call to
parport_pc_unregister_port. Note that some parport devices have its
'struct device' parent, known as port->dev.  And when port->dev is a
platform device, it is destroyed in parport_pc_exit too.

Now, when parport_pc_unregister_port is called for a going port,
drv->detach(port) is called for every parport driver in the system.
ppdev can be one of them. ppdev's detach() tears down its per-port
sysfs directory, which established port->dev as a parent earlier.

But since parport_pc_exit kills port->dev parents before unregisters
ports proper, ppdev's sysfs directory has no living parent anymore.
This results in the following warning:

WARNING: CPU: 1 PID: 785 at fs/sysfs/group.c:219 sysfs_remove_group+0x9b/0xa0
sysfs group ffffffff81c69e20 not found for kobject 'parport1'

It is also easily reproducible on qemu with two dummy ports '-parallel
/dev/null -parallel /dev/null'.

So switch the order of killing the two structures. But since port is
freed by parport_pc_unregister_port, we have to remember port->dev
in a local variable.

Perhaps nothing worse than the warning happens thanks to the device
refcounting. We *should* be on the safe side.

Matwey V. Kornilov 0ae39cc981 parport: parport_pc: Implement architecture and device check to cut off false-positives
We definitely know that only x86 (32-bit) architecture is affected by the issue, so implement a stub instead of the actual check for other architectures.

We also know that motherboard LPT chipset is affected, so the port is either come from
  parport_pc_init (when `io' module param is used) or
  parport_pc_find_isa_ports (when default LPT ports are probbed: 0x378, 0x278, 0x3bc).
In both cases the port considered as 'legacy' and `dev' member of struct parport is NULL. See also comments for `struct parport' in parport.h

Sebastian Andrzej Siewior d6a484520c parport: parport_pc: remove double PCI ID for NetMos
In commit 85747f ("PATCH] parport: add NetMOS 9805 support") Max added
the PCI ID for NetMOS 9805 based on a Debian bug report from 2k4 which
was at the v2.4.26 time frame. The patch made into 2.6.14.
Shortly before that patch akpm merged commit 296d3c783b ("[PATCH] Support
NetMOS based PCI cards providing serial and parallel ports") which made
into v2.6.9-rc1.
Now we have two different entries for the same PCI id.
I have here the NetMos 9805 which claims to support SPP/EPP/ECP mode.
This patch takes Max's entry for titan_1284p1 (base != -1 specifies the
ioport for ECP mode) and replaces akpm's entry for netmos_9805 which
specified -1 (=none). Both share the same PCI-ID (my card has subsystem
0x1000 / 0x0020 so it should match PCI_ANY).

While here I also drop the entry for titan_1284p2 which is the same as
netmos_9815.

Since commit 7106b4e3 ("8250: Oxford Semiconductor Devices") the debug
print of the device id does no longer match the real device if it is
located in the "enum" behind oxsemi_pcie_pport. The reason is that the
code assumes that each id contains one entry in the PCI table.
The fix is to lookup the currently used id from the id-> parameter.

This change removes the use of __devinit, __devexit_p, __devinitdata,

Jiri Kosina 9fdbdd062b parport_pc: release IO region properly if unsupported ITE887x card is found
sio_ite_8872_probe() bails out if it detects no-parallel (1S, 2S) or
unknown card.

It doesn't call release_region() on the previously allocated resource
though.  This causes

  (a) leak of the resource
  (b) kernel oops when parport module is removed and /proc/ioports is read. This
      is because the string that has been associated to the IO port region
      is a static char array inside the already removed module.

Let's call release_region() properly before baling out.

FUJITA Tomonori dfa7c4d869 parport_pc: set properly the dma_mask for parport_pc device
parport_pc_probe_port() creates the own 'parport_pc' device if the
device argument is NULL. Then parport_pc_probe_port() doesn't
initialize the dma_mask and coherent_dma_mask of the device and calls
dma_alloc_coherent with it. dma_alloc_coherent fails because
dma_alloc_coherent() doesn't accept the uninitialized dma_mask:

http://lkml.org/lkml/2009/6/16/150

Long ago, X86_32 and X86_64 had the own dma_alloc_coherent
implementations; X86_32 accepted a device having dma_mask that is not
initialized however X86_64 didn't. When we merged them, we chose to
prohibit a device having dma_mask that is not initialized. I think
that it's good to require drivers to set up dma_mask (and
coherent_dma_mask) properly if the drivers want DMA.

Jens Rottmann e2434dc1c1 parport_pc: after superio probing restore original register values
CONFIG_PARPORT_PC_SUPERIO probes for various superio chips by writing
byte sequences to a set of different potential I/O ranges.  But the
probed ranges are not exclusive to parallel ports.  Some of our boards
just happen to have a watchdog in one of them.  Took us almost a week
to figure out why some distros reboot without warning after running
flawlessly for 3 hours.  For exactly 170 = 0xAA minutes, that is ...

Fixed by restoring original values after probing.  Also fixed too small
request_region() in detect_and_report_it87().

Linus Torvalds 4ed919014e parport_pc: make sure to release IO ports after probing for IT87XX
Commit f63fd7e299 ("parport_pc: detection
for SuperIO IT87XX POST") only released the IO port region on success,
not when the probe for the IT87XX chip failed.

That caused not only a reserved region to leak, but also caused an oops
when the driver module was unloaded and somebody tried to cat
/proc/ioports - because the string that was assigned to the IO port
region was a static string in the module virtual address area.

The IO port range requested by parport_pc.c:sio_ite_8872_probe is too small.
The IO-ports of ttyS1 (0x2f8) will be missconfigured by the ITE-chip.  The ITE
starts looking for the chip a 0x2a0.  An IO-portrange of 32 will not overwrite
the ports of ttyS1.  Therefore register 0x60 should be written with
0xe5000000, enabling the ITE and setting IO-portsize to 32 bytes.

Give legacy parallel ports a platform device in the device tree.

This is a quick and dirty implementation; it doesn't actually convert the

device creation).  But at least parallel port device drivers will finally have
a device to work with.

David Brownell c15a3837d2 parport->dev driver model support
Currently a parport_driver can't get a handle on the device node for the
underlying parport (PNPACPI, PCI, etc).  That prevents correct placement of
sysfs child nodes, which can affect things like power management.

This patch adds a field to "struct parport" pointing to that device node, and
updates non-legacy port drivers to initialize that device pointer.  That field
replaces the analagous PCI-only support in parport_pc.
