      [PATCH] USB gadget: gadget zero, simplified controller-specific configuration · 3e4a8764
      David Brownell authored
      This removes several controller-specific #define, and
      converts to using the config_buf utilities.  Depends
      on the patch I submitted yesterday.  Looking simpler!
      
      
      Simplify "gadget zero" compile-time configuration.
      
      This removes several controller-specific compile-time config options;
      the others are about to be autoconfigured.
      
       - HIGHSPEED replaced by CONFIG_USB_GADGET_DUALSPEED
       - Default to self-powered operation
       - There's no UI for remote wakeup
      
      It also uses the new config_buf utilities, so it's a bit easier to see
      what's really going on (this driver implements four configurations).

      [PATCH] USB: usb buffer allocation shouldn't require DMA · 29a611ab
      David Brownell authored
      Deepak's recent dma_pool changes accidentally assumed that
      all HCDs use DMA.  The fix is simple:  use kmalloc/kfree
      when there's no DMA.

      [PATCH] USB: usbtest updates (new firmware) · 529ba76c
      David Brownell authored
      This includes some small updates to "usbtest", mostly
      from Martin Diehl.  Please merge.
      
      
      
      usbtest updates, supporting new firmware
      
          - Support the new usbtest_fw-20040305 EZ-USB firmware,
            which renumerates and handles full speed ISO transfers.
            (From Martin Diehl.)
      
          - Minor cleanups:  use dev_dbg(), let some slightly-off
            devices work in the control queueing test.
      
          - Be pickier about unlink tests:  insist that async
            and sync unlinks give the appropriate fault code.

      [PATCH] USB: usb_unlink_urb() has distinct "not linked" fault · 6df6a80d
      David Brownell authored
      This gets rid of an often-bogus diagnostic, and lets
      at least the unlink test code recover reasonably when
      it hits that brief window while another CPU has gotten
      the complete() callback but hasn't yet resubmitted.
      
      
      
      Return distinct code when unlinking an urb that's not linked.
      
      This lets drivers handle this fault sanely, when they need to.
      Gets rid of annoying non-error messages about drivers that unlink
      in disconnect() even when the urb isn't linked.

      [PATCH] USB gadget: dualspeed {run,compile}-time flags · 2328fb17
      David Brownell authored
      This is the first several autoconfig patches; please merge.
      This particular one abstracts dual-speed (high and full)
      support.
      
      
      Support some more autoconfiguration for gadget drivers.
      
          Run-time:
      	* Add gadget->is_dualspeed flag for controllers to set.
      	* Tested by "ethernet" gadget, to decide whether certain
      	  operations are errors or not.
      	* Turned on by net2280.
      
          Compile-time
      	* Generic CONFIG_USB_GADGET_DUALSPEED, not net2280-specific.
      	* Used by "ethernet" gadget, to decide whether to
      	  include extra code and data for dual-speed support.
      	* Turned on by net2280.
      
      The basic idea behind this, and other autoconfig patches yet to come,
      is minimizing the controller-specific compile-time configuration
      needed by gadget drivers.

      [PATCH] USB: Remove interface/altsetting assumptions from usb-midi · c5cd1f9d
      Alan Stern authored
      This patch makes the usb-midi driver use usb_ifnum_to_if(), thereby
      removing assumptions about which interface is stored in which array entry.
      Similarly, it stores the bAlternateSetting value rather than the array
      index for an altsetting entry.
      
      Like the earlier patch for the audio driver, this also changes the driver
      to use the in-memory rawdescriptor buffer rather than reading a
      configuration descriptor from the device.  Unlike that earlier patch, this
      time there's no question that the deallocation of the buffer is done
      correctly.  (I suspect the audio driver just left out a call to kfree.)

      No it isn't.  But maybe the attached patch would clarify what's
      really going on:  CONFIG_USB is the host side, and CONFIG_USB_GADGET
      is the peripheral side.

      [PATCH] USB brlvger: Driver obsoleted by rewrite using usbfs · 25a1f19a
      Stéphane Doyon authored
      We have rewritten the brlvger (Tieman Voyager USB Braille display) driver
      so that it works from user-space through usbfs. It appears to work just as
      well as the in-kernel driver.
      
      The brlvger driver in the 2.6.x kernel is now obsolete and should be
      removed. The attached patch against 2.6.3 does this. Please apply.
      NB: The following files are completely deleted:
          Documentation/usb/brlvger.txt
          drivers/usb/misc/brlvger.c
          include/linux/brlvger.h
      
      The new Voyager driver is available (stil under GPL) as part of BRLTTY,
      starting with version 3.5pre1 (http://mielke.cc/brltty).
      Thanks to Dave Mielke who implemented BRLTTY's usbfs functionality, among
      lots of other stuff.

      You're right, it is a mess.  Beats me why they didn't use a plain old
      "for" statement to do that altsetting loop.  Probably the most confusing
      part is where the code needlessly resets intf->act_altsetting.
      
      Anyway, this patch sets things right.  I haven't tried to compile it, but
      any errors ought to be pretty small, obvious, and easy to fix.
      
      My intention was to go through the files under driver/usb (in alphabetical
      order!) and then do the ones outside that subtree -- I've got a little
      list.  But it's no problem to take care of this one first.

      [PATCH] USB UHCI: restore more state following PM resume · 593f48d6
      Alan Stern authored
      Some systems don't save the internal state of the UHCI registers across a
      PM suspend/resume cycle very well.  This patch saves & restores the
      Frame Number and the Framelist Base Address registers (in addition to the
      Interrupt Enable register, which was added separately in a recent patch.)

      [PATCH] USB: Remove interface/altsettings assumption from audio driver · 2d5185c7
      Alan Stern authored
      This patch updates the USB audio class driver to use the usb_ifnum_to_if()
      and usb_altnum_to_altsetting() routines, thereby removing assumptions
      about which interface or altsetting is stored in which array entry.
      
      It also simplifies the driver's probe() routine by using the raw
      configuration descriptor already loaded into memory instead of reading the
      descriptor from the device.  Now, either the current driver has a bug and
      never deallocates the buffer used to hold the descriptor, or else I've
      introduced a double-free error.  There's no obvious place where the buffer
      gets freed, but it's hard to be certain.
      
      It would be good if someone could try out this patch.  I can't test it,
      not having any USB audio devices handy.  If the double-free error is
      present, it will show up when the device is disconnected and the
      configuration data is released.

      [PATCH] USB: Update USB class drivers · 40c72cb0
      Alan Stern authored
      This patch makes the necessary updates to the bluetty, cdc-acm, and usblp
      class drivers for the new interface/altsetting paradigm.  The changes are
      quite small.
      
      Unfortunately, the audio and usb-midi drivers are in much worse shape.
      They will require more in-depth hacking, to come later...

      [PATCH] Fix nobh_prepare_write() race · b12088bf
      Andrew Morton authored
      Dave Kleikamp <shaggy@austin.ibm.com> points out a race between
      nobh_prepare_write() and end_buffer_read_sync().  end_buffer_read_sync()
      calls unlock_buffer(), waking the nobh_prepare_write() thread, which
      immediately frees the buffer_head.  end_buffer_read_sync() then calls
      put_bh() which decrements b_count for the already freed structure.  The
      SLAB_DEBUG code detects the slab corruption.
      
      We fix this by giving nobh_prepare_write() a private buffer_head end_o
      handler which doesn't touch the buffer's contents after unlocking it.
