Recent alterations to the gdth_fill_raw_cmd() path no longer set the
sg_ranz field for zero transfer commands. However, this field is used
lower down in the function to initialise ha->cmd_len to the size of
the firmware packet. If this uninitialised field contains a bogus
value, ha->cmd_len can become much larger than the actual firmware
packet and end up oopsing in gdth_copy_cmd() as it tries to copy this
huge packet to the device (usually because it runs into an unallocated
page).
The fix is to initialise the sg_ranz field to zero at the start of
gdth_fill_raw_cmd().

This fix's an oops during driver load time. mptsas_probe calls
mpt_attach(over in mptbase.c). Inside that call, we read some
manufacturing config pages to setup some defaults. While reading the
config pages, the firmware doesn't complete the reply in time, and we
have a timeout. The timeout results in hardreset handler being called.
The hardreset handler calls all the fusion upper layer driver reset
callback handlers. The mptsas_ioc_reset function is the callback
handler in mptsas.c. So where I'm getting to, is mptsas_ioc_reset is
getting called before scsi_host_alloc is called, and the pointer ioc->sh
is NULL as well as the hostdata.

If a PCI error is detected that cannot be recovered from, there
will be a double call of lpfc_pci_remove_one(), with the second call
resulting in a null-pointer dereference. The first call occurs in
lpfc_io_error_detected(), and the second call during pci device
remove. This patch eliminates the first call; its un-needed.

This reverts commit d2487cb425.
Russell King points out that it's obviously bogus, and I have to agree.
Not only does "irq" not even exist in that scope, but we obviously need
to free the irq that we actually requested, and that's IRQ_USB.

Delay the read of the EC status register until
after the event that caused it occurs -- otherwise
it is possible to read and act on stale status that was
associated with the previous event.
Do this with a perpetually incrementing "event_count" to detect
when a new event occurs and it is safe to read status.
There is no workaround for polling mode -- it is inherently
exposed to reading and acting on stale status, since it
doesn't have an interrupt to tell it the event completed.

Here is a patch adding the PID for the FT232RL to ftdi_sio. The patch
generates a warning during compilation because get_ftdi_divisor doesn't
explicitly handle the FT232RL with this patch, so I guess you don't want
to use it in its current state. It is all I could come up with with the
knowledge I have of the drivers at the moment, though, and I hope you
can have some use for it at least. It works fine with my DLP-TILT with
an FT232RL.

I encountered some problems with the airprime driver in use with a Novatel
Merlin XU870:
Closing an open Connection to e.g. /dev/ttyUSB0 doesn't reset the
RTS/DTR lines of the Modem. Consequently, when I use minicom to
establish a connection by "ATD*99#" the modem doesn't hang up even if i
exit minicom and so I cannot reuse the modem unless I remove it and plug
it in again.
With the attached patch, the RTS/DTR lines are resetted on a close. The
code was mainly taken from the option.c driver.
Convert all the port specific code in attach / shutdown to use the new
port_probe / port_register callbacks from device_register /
device_unregister allowing adding the sysfs attributes to be added at
the correct time and to the serial port device itself, instead of to
the unadorned usb device, avoiding a NULL dereference.

I've developed some devices with FTDI chips (FT232xx). FTDI was so kind
to give some own PID's which I can use together with their VID. Some of
the devices are already very popular here and I have customers from
universities, institutes .....
I use the FTDI VID 0x0403. My PID's are:
0xff38 - IBS US485 (USB<-->RS422/485 interface)
0xff39 - IBS PIC-Programmer
0xff3a - IBS Card reader for PCMCIA SRAM-cards
0xff3b - IBS PK1 - Particel counter
0xff3c - IBS RS232 - Monitor
0xff3d - APP 70 (dust monitoring system)
0xff3e - IBS PEDO-Modem (RF modem 868.35 MHz)
0xff3f - future device
The company is "IBS Ing.-Buero Schleusener".

This patch (as863) fixes a problem encountered sometimes when resuming
a port on a UHCI controller. The hardware may turn off the
Resume-Detect bit before turning off the Suspend bit, leading usbcore
to think that the port is still suspended and the resume has failed.
The patch makes uhci_finish_suspend() wait until both bits are safely
off.

This will help people troubleshoot when ACPI isn't working. Status quo is

implements ACPI but not DMI. This is actually fairly common on embedded
