This patch (as1110) reverts an earlier patch meant to help with
Wireless USB host controllers.  These controllers can have bulk
maxpacket values larger than 512, which puts unusual constraints on
the sizes of scatter-gather list elements.  However it turns out that
the block layer does not provide the support we need to enforce these
constraints; merely changing the DMA alignment mask doesn't help.
Hence there's no reason to keep the original patch.  The Wireless USB
problem will have to be solved a different way.

In addition, there is a reason to get rid of the earlier patch.  By
dereferencing a pointer stored in the ep_in array of struct
usb_device, the current code risks an invalid memory access when it
runs concurrently with device removal.  The members of that array are
cleared before the driver's disconnect method is called, so it should
not try to use them.

This patch (as1109b) makes USB-Persist more resilient to errors.  With
the current code, if a normal resume fails, it's an unrecoverable
error.  With the patch, if a normal resume fails (and if the device is
enabled for USB-Persist) then a reset-resume is tried.

This fixes the problem reported in Bugzilla #10977.

A couple of USB register initializations had to be changed on MPC85xx
platforms.  This is due to the internal SoC buses being different on
MPC83xx SoCs vs MPC85xx SoCs.

We currently handle this via an ifdef since 83xx and 85xx are mutually
exclusive kernel builds.

Fix pointer/int cast in USB devio code, and thus avoid a compiler warning.

A void* data argument passed to bus_find_device() and thence to match_devt()
is used to carry a 32-bit datum.  However, casting directly between a u32 and
a pointer is not permitted - there must be an intermediate cast via (unsigned)
long.

This was introduced by the following patch:

This patch (as1107) fixes a small bug in the usbfs registration and
unregistration code.  It avoids leaving an error value stored in the

This patch (as1106) fixes a race between opening and unregistering
device files in usbfs.  The current code drops its reference to the
device and then reacquires it, ignoring the possibility that the
device structure might have been removed in the meantime.  It also
doesn't check whether the device is already in the NOTATTACHED state
when the file is opened.

USB device files are accessible in two ways: as files in usbfs and as
character device nodes.  The two paths are supposed to behave
identically, but they don't.  When the underlying USB device is
unplugged, disconnect signals are sent to processes with open usbfs
files (if they requested these signals) but not to processes with open
device node files.

This patch (as1104) fixes the bug by moving the disconnect-signalling
code into a common subroutine which is called from both paths.
Putting this subroutine in devio.c removes the only out-of-file
reference to struct dev_state, and so the structure's declaration can
be moved from usb.h into devio.c.

Finally, the new subroutine performs one extra action: It kills all
the outstanding async URBs.  (I'd kill the outstanding synchronous
URBs too, if there was any way to do it.)  In the past this hasn't
mattered much, because devices were unregistered from usbfs only
when they were disconnected.  But now the unregistration can also
occur whenever devices are unbound from the usb_generic driver.  At
any rate, killing URBs when a device is unregistered from usbfs seems
like a good thing to do.

This patch (as1024) takes care of a FIXME issue: Drivers that don't
have the necessary suspend, resume, reset_resume, pre_reset, or
post_reset methods will be unbound and their interface reprobed when
one of the unsupported events occurs.

This is made slightly more difficult by the fact that bind operations
won't work during a system sleep transition.  So instead the code has
to defer the operation until the transition ends.

Various cleanups and fixes to the i2c code in ohci-pnx4008:
* Delete empty isp1301_command. The i2c driver command implementation
  is optional, so there's no point in providing an empty
  implementation.
* Give a name to isp1301_driver. I'm surprised that i2c-core accepted
  to register this driver at all. I've chosen "isp1301_pnx" as the
  name, because it's not a generic ISP1301 driver (much like the
  isp1301_omap driver.) We might want to make the name even more
  specific (but "isp1301_ohci_pnx4008" doesn't fit.)
* The ISP1301 is definitely not a hardware monitoring device.
* Fix a memory leak on failure in isp1301_attach. If
  i2c_attach_client fails, the client is not registered so
  isp1301_detach is never called and the i2c_client memory is lost.
* Use strlcpy instead of strcpy.

USB debug port only supports 8 byte rx/tx packets. Although spec implies that
"if a packet larger than eight bytes is received from the remote computer, the
device must break the larger packet into eight-byte packets before sending the
data to the Debug Port", the real PLX NET20DC device does not handle it right -
data is corrupted on debug port end if serial interface sends >8 byte urbs.
Patch below fixes the issue by limiting tx urb to 8 byte.
