514fb84e1c [PARISC] [MUX] Get the hversion directly from the parisc_device
Willy pointed out the hversion is already stored
in the parisc_device, so I do not need to extract
this information directly from the IODC data.
Also by using the information in the parisc_device
I can avoid re-reading the IODC data for the Muxes
with specifed port counts.

6142544584 [PARISC] [MUX] Correctly report the number of available ports
This patch adds a new function to return the actual number
of ports available.  Some of the built-in Muxes return the
number of supported ports, but not all of these port are
available for use.

752b940359 [PARISC] [MUX] Detect multiple cards in the correct order
This patch follows the example of the 8250_gsc
driver by probing for specific built-in Mux
cards first.  This allows the system to preserve
the correct detection order with multiple Mux
cards.

c380f05726 [PARISC] [MUX] Make the Serial Mux driver work as module
The following updates are based off a patch from willy:
  * Removal of the mux_card list.
  * Add the mux_remove function.

Other updates:
  * Re-organize the driver structure a bit to make the
    mux_init and mux_exit functions more symmetrical.
  * Added the del_timer.
  * Unregistered the console.

At this point I can insmod, rmmod, and re-insmod the
mux without any failures.

7174d85260 [ARM] 3983/2: remove unused argument to __bug()
It appears that include/asm-arm/bug.h requires include/linux/stddef.h
for the definition of NULL. It seems that stddef.h was always included
indirectly in most cases, and that issue was properly fixed a while ago.

Then commit 5047f09b56 incorrectly reverted
change from commit ff10952a54 (bad dwmw2)
and the problem recently resurfaced.

Because the third argument to __bug() is never used anyway, RMK suggested
getting rid of it entirely instead of readding #include <linux/stddef.h>
which this patch does.

ed30c26ee8 ieee1394: Consolidate driver registering
This patch consolidates some bookkeeping for driver registering. It
closely models what pci_register_driver() does. The main addition is
that the owner of the driver is set, so we get a proper symlink
for /sys/bus/ieee1394/driver/*/module.

Also moves setting of name and bus type into nodemgr. Because of this,
we can remove the EXPORT_SYMBOL for ieee1394_bus_type, since it's now
only used in ieee1394.ko.

8252bbb136 ieee1394: nodemgr: fix deadlock in shutdown
If "modprobe ohci1394" was quickly followed by "modprobe -r ohci1394",
say with 1 second pause in between, the modprobe -r got stuck in
uninterruptible sleep in kthread_stop.  At the same time the knodemgrd
slept uninterruptibly in bus_rescan_devices_helper.  That's because
driver_detach took the semaphore of the PCI device and
bus_rescan_devices_helper wanted to take the semaphore of the FireWire
host device's parent, which is the same semaphore. This was a regression
since Linux 2.6.16, commit bf74ad5bc4,
"Hold the device's parent's lock during probe and remove".

The fix (or workaround) adds a dummy driver to the hpsb_host device. Now
bus_rescan_devices_helper won't scan the host device anymore.  This
doesn't hurt since we have no drivers which will bind to these devices
and it is unlikely that there will ever be such a driver.  The dummy
driver is befittingly presented as a representation of ieee1394 itself.
