Here is a little patch that remove procfs stuff in pci_hotplug_core.c
Remove /proc entry for pci_hotplug_core.

These were pointed out by "dan carpenter" <error27@email.com>
from his smatch tool.

This prevents reporting processes as having started in the future, after
32 bit jiffies wrap.

Use 64 bit jiffies for reporting uptime.

Provide a sane way to avoid unneccessary locking on 64 bit platforms,
and a 64 bit analogous to "jiffies_to_clock_t()".

 - conversion of remaining drivers to generic device model
 - more of sfr's compat stuff
 - eliminate some bogus syscalls
 - update for MUX driver
 - beginnings of new module code
 - tell the keyboard driver about CONFIG_PARISC

This patch clears out the device queue when a unit is removed.

This code implements the setting of devices offline during the removal
phase.

This patch makes us hold the host reference count a little bit longer in
the /proc interface code.  We were releasing it too early before.

  speedtouch: reject outgoing packets earlier when the firmware is not loaded.

  speedtouch: allocate send urbs in udsl_usb_probe rather than in udsl_usb_data_init.
  Since this diminishes udsl_usb_data_init down to almost nothing, roll it into the one
  place it was used.  Get rid of the semaphore Oliver put it - it is no longer needed.

  speedtouch: change data_started to firmware_loaded, which is what it actually
  means, plus some minor related changes.

  speedtouch: a pile of cosmetic changes to make me feel happier (no code changes).

  speedtouch: wait for receive urb completion handlers to finish after calling
  usb_unlink_urb.

  speedtouch: more robust handling of receive urb failure: retry failed urbs whenever
  a new connection is opened.  This should work well with pppd's persist option.

Rediffed version of the original patch - no sk_buff on the stack this time.

  speedtouch: recycle the receive urb's buffer.  Currently, every time a receive urb
    completes, its old buffer is thrown away and replaced with a new one.  This patch
    performs the minor changes needed to reuse the old buffer.

  speedtouch: move all processing of receive urbs to udsl_atm_processqueue.  This has
  several advantages, as will be seen in the next few patches.  The most important is
  that it makes it easy to reuse of the urb's buffer (right now a new buffer is
  allocated every time the urb completes).  By the way, this patch is much smaller than
  it looks: most of the bulk is due to indentation changes.

This patch prints the vendor + product ids of the scanner after it has
been successfully detected.

Also the annoying error message about "Scanner device is already open"
was downgraded to a dbg. Scanning for devices while one scanner device
was open produced several 100 error messages in syslog.

This patch changes the maintainer from Brian Beattie to Henning
Meier-Geinitz and adds a link to the documentation and website.

This is a minor cleanup to convert 8 spaces into tabs.  There is no
functional change here.

This patch removes the US_FL_DEV_ATTACHED flag, which is now rendered
obsolete by the new hotplug system.

It also adds a comment or two about areas of code that need to be
re-examined.

This patch does the following:
(o) Add comments showing what needs to be done to complete the hot-unplug
    system.
(o) Add a BUG_ON() for (what is now) a critical failure case.
(o) Make certain that a debug print happens even if a usb_get_intfdata()
    crashes.
(o) Add an un-necessary up() to balance a down, for the auto-code-checkers.

It should fix the OOPS on attach.

This fixes a silly error where I fail to initialize a pointer early enough
for the scanning code.  If this isn't a perfect example of why
scsi_register() and scsi_add_host() aren't two separate functions, I don't
know what is.  :)

Oh, and I added a couple of comments, too.

  -  Fix an OOPS by moving the setting of the hostdata[] pointer to _before_
     the device scan starts.

This patch goes on top of the last one.  It fixes a typo in the test for
scsi_register() failure.

  -- reversed the logic of failure test for scsi_register()

The attached patch is my first implementation of SCSI hotplugging.

It's only been tested that it compiles, as I can't get the current
linux-2.5 tree from linuxusb to boot.  It dies _very_ early.  Greg, I'm not
sure if you'll want to apply this.  Linus seemed to want this very much,
and it is 2.5.x... I say go for it, but I can understand if you have
reservations.

I would definately like to see this tested by anyone who can get a kernel
to boot.

This patch is quite large.  Lots of things had to be changed.  Among them:

(o) The proc interface now uses the host number to look up the SCSI host
    structure, and then finds the usb-storage structure from that.
(o) The SCSI interface has been changed.  The code flow is now much
    clearer, as more work is done from the USB probe/detach functions than
    from auxillary functions.
(o) Names have been changed for newer conventions
(o) GUIDs have been removed
(o) The linked-list of devices has been removed, and it's associated
    semaphore
(o) All code dealing with re-attaching a device to it's old association has
    been removed
(o) Some spaces changed to tabs
(o) usb-storage now takes one directory under /proc/scsi instead of
    one per virtual-HBA
(o) All control threads now have the same name.  This could be changed back
    to the old behavior, if enough people want it.

Known problems:
(o) Testing, testing, testing
(o) More dead code needs to be cut
(o) It's a unclear how a LLD is supposed to cut off the flow of
    commands, so that the unregister() call always succeeds.  SCSI folks
    need to work on this.
(o) Probing needs to be broken down into smaller functions, probably.

Thanks to Matt Dharm and David Brownell for tracking this bug down.
