moved files to different subdirectories to make try to make sense
of the current mess, and to allow usb client drivers to integrate into
the tree easier.

Periodically folk have run into problems where usb-ohci oopses
due to device refcount bugs ...
This is a minor patch to move the sanity check out of usb-ohci
into the generic bits of usbcore. There are comments that
suggest a path for a more comprehensive approach too.
Applies cleanly against 2.5.7 and I've been testing with it
for a while. I can't think of any reason it shouldn't also go
into 2.4, beyond the patch not applying cleanly there ... :)

As it's linked after PCI, usb_init() will be called after pci_init(),
which is an subsys_initcall, too. Subtle, but right.
|
|
- removed debugging statement in usb_free_urb() that I
accidentally left in :(
|
|
- Moves 8 functions from usb.[hc] to hcd.[hc]
- Also moves some data structures and types
- Now usbdevfs and "old" HCDs #include "hcd.h"
- Minor tweaks to the "hcd" layer (one less FIXME)
- Minor kernel doc and comment cleanups
Basically this continues moving the HCD-only functionality
out of the way of normal USB device drivers. Converging
"usb_bus" and "usb_hcd" (later!) will be a bit easier too.
I did basic sanity tests, there's little to break ... :)
There are still a few functions in usb.c that aren't for
general driver use. They're mostly for enumeration,
in areas where the hub driver and HCD root hubs
need to do various kinds of magic. It wasn't clear
how to decouple those, they can certainly wait.

- Fix for removing a device that does not have a driver bound to it.

this is a patch to prevent usb_set_interface() from erroneously resetting
the toggles for all endpoints instead of only the affected ones from the
requested interface/altsetting. I've also added some missing parentheses
to related macros in usb.h as I prefered not to take special care for
nasty side-effects ;-)
Patch below was created against 2.4.18-pre9 (with some lines of offset it
applies to 2.5.4-pre5 as well).
Tested in multi-interface configuration to provide evidence it:
* correctly identifies the affected endpoints and resets the toggles
* doesn't touch endpoints from other interfaces
* provides correct handling of shared EP0
* solves an issue I had with 2.4.18-pre9 where setting one interface
occasionally caused transfers on other interface to hang due to lost
toggle synchronisation
Despite being a pure bugfix, well localized and (IMHO) pretty obviously
correct wrt. USB-spec, I'd like to suggest including this in early
2.4.19-pre. Just in case some existing driver would somehow workaround
the currently wrong behavior and might break with this fix. And it's
not very urgent right now, as we are probably close to 2.4.18-rc1.
Regards,
Martin

Big bits first, I'll redo the smaller bits tomorrow after some sleep.
Same as last time, rediffed against pre5

- initial add of the "int mem_flags" call to the usb_submit_urb() call

Here's a patch against 2.5.3 for the USB core that fixes a possible
initialization bug for some platforms when allocating a new usb, and
changes the warning level on a message (it isn't an error.) This patch
was done by Oliver Neukum and David Brownell.
