Fix misplaced quirk entries for devices driven by hid-pl driver. The
devices shouls be only blacklisted by generic HID driver, not completely
ignored.

Commit 0794469da3f7b2093575cbdfc1108308dd3641ce: ("ACPI: struct device -
replace bus_id with dev_name(), dev_set_name()") introduced a bug by
testing 'dev_name(ldev)' instead of 'ldev->bus' for NULL when printing
out the bus information.
So if ldev->bus was NULL, we'd oops.

Some devices have no input interrupt endpoint. These won't be handled
by usbhid, but currently they are not refused and reside on hid bus.
Perform this checking earlier so that we refuse to control such
a device early enough (and not pass it to the hid bus at all).

`stop' left out usbhid->urb* pointers and so the next `start' thought
it needs to allocate nothing and used the memory pointers previously
pointed to. This led to memory corruption and device malfunction.
Also don't forget to clear disconnect flag on start which was left set
by the previous `stop'.
This fixes

echo DEVICE > /sys/bus/hid/drivers/DRIVER/bind
failures.

Use single threaded work queue for hid_compat
I doubt HID really needs to scale over multiple CPUs. So only use a
single threaded workqueue for HID_COMPAT. This avoids some excessive
thread use on systems with a larger number of CPUs.

Under qemu there is a race between the TDxE read-and-clear and the SCxTDR
write. While on hardware it can be gauranteed that the read-and-clear
will happen prior to the character being written out, no such assumption
can be made under emulation. As this path happens with IRQs off and the
hardware itself doesn't care about the ordering, move the SCxTDR write
until after the read-and-clear.

This bug were supposed to be fixed by 5ba2f67afb02c5302b2898949ed6fc3b3d37dcf1,
where a call to NULL happens.
Not all tvaudio chips allow controlling bass/treble. So, the driver
has a table with a flag to indicate if the chip does support it.
Unfortunately, the handling of this logic were broken for a very long
time (probably since the first module version). Due to that, an OOPS
were generated for devices that don't support bass/treble.
This were the resulting OOPS message before the patch, with debug messages
enabled:

Better to reference directly the data.

This patch checks for volume, bass, treble, set mode and get mode
callbacks before actually enabling the code that would use them.
Instead of aborting the driver for load, this patch will allow it to
load with a reduced number of functionatities.
This prevents OOPS if some board entry is missing a needed callback.

generic_checkmode() were called, via a callback, for some tvaudio chips.
There's just one callback code used on all those boards. So, it makes no
sense on keeping this as a callback.
Since there were some OOPS reported on tvaudio on kerneloops.org, this
patch removes this callback, adding the code at the only place were it
is called: inside chip_tread. A flag were added to indicate the need for
a kernel thread to set stereo mode on cards that needs it.
Using this more direct approach simplifies the code, making it more
robust against human errors.

In ccw_device_move_to_orphanage(), a replacing ccw_device
is searched via get_{disc,orphaned}_ccwdev_by_dev_id()
which obtain a reference on the returned ccw_device.
This reference must be given up again after the device
has been moved to its new parent.

The current virtio model on s390 has the descriptor page above the main
memory. The guest virtio detection will oops if the mem= parameter is
used to reduce/change the memory size.
We have to use real_memory_size instead of max_pfn to detect the virtio
descriptor pages.

dpt_i2o.c::adpt_i2o_to_scsi() reads the value at (reply+5) which
should contain the length in bytes of the transferred data. This
would be correct if reply was a u32 *. However it is a void * here,
so we need to read the value at (reply+20) instead.
The value at (reply+5) is usually 0xff0000, which is apparently
'large enough' and didn't cause any trouble until 2.6.27 where

Drivers want to be able to return DID_TRANSPORT_DISRUPTED and
have it do the right thing for commands like tape and passthrouh
as far as retries go. The LLDs previously used DID_BUS_BUSY or DID_ERROR
which followed the cmd->retries limit, but DID_TRANSPORT_DISRUPTED
was skipping that check so it could have caused a problem with tape
commands.
This patch has DID_TRANSPORT_DISRUPTED check the cmd->retries/cmd->allowed.

Fix multiple problems found in the hexdump data:
- length calculation was wrong, traces were incomplete
- FC payloads were dumped in different record than the output
function tried to read
- minor fixes in output
- allow complete RSCN traces (up to 1024 bytes according to spec)

If an open port fsf request times out (in erp) the
corresponding erp_action member of the fsf
request need to set to NULL. If the port structure
will be removed later-on there will be still a
reference in the fsf request to the non existing
erp_action otherwise.

Attaching a unit immediately after setting the adapter online should
be possible. The problem right now is that the port_scan runs from a
workqueue and has not finished when the set_online call returns and
the sysfs structures for the ports are not available yet. Fix that by
waiting for the port scan to complete.
