[PATCH] uhci-hcd.c shouldn't halt control endpoints

uhci-hcd.c currently calls usb_endpoint_halt() in the td_error: path of uhci_result_control(). David Brownell told me that "control endpoints don't halt" and that this is wrong. The patch below fixes this and allows my Belkin Universal UPS to work. [Although it still prints lots of "drivers/usb/input/hid-core.c: ctrl urb status -32 received" messages.] Greg K-H, could you merge this if it looks right? David mentioned that the same bug exists in 2.4.x.

[PATCH] ehci, more diagnostics use dev_*() macros

This reduces the quantity of messages, by using the newer dev_*() macros, and by deleting some messages.

[PATCH] ehci-hcd, handle async_next register correctly

This patch should improve behavior of the EHCI driver, particularly on VIA hardware.

- A more careful reading of the EHCI spec turns up requirements not to change this register's value while the async schedule is enabled. That means in effect that it must never point to a QH that'd get unlinked ... driver now uses a dedicated QH.

- Disables async schedule a bit faster: after 50msec idle, not 330msec idle.

- Streamline the "can't init memory" failure path.

- Start to use the dev_dbg()/dev_info()/... macros in more places.

This version acts a bunch happier than the previous version, removing some failure modes I could never quite convince myself were hardware (they weren't!) I suspect it'll remove a lot of the "it hangs" failures that some folk have reported (mostly on 2.4 though).

[PATCH] reduce debug message volume

This reduces the debug message volume a bit, mostly by using the new dev_dbg() macros instead of the usb dbg() ones in some places during HCD init/shutdown. Likewise dev_info().

[PATCH] usb-storage doesn't say clear_halt WORKED

This removes a printk that's been cluttering up my logs, especially when I do things like 'mkfs -c ...' it doesn't seem to be needed any more.

[PATCH] usbfs: more list cleanups

Here is a small cleanup patch for 2.5 that goes on top of my previous ones. It makes devio.c use the list traversal macros from list.h.

[PATCH] module unload race with usb serial drivers

the serial subdrivers may be unloading while we open. This patch against 2.5 guards against that.
