2008-10-30tty: Fix USB kref leakAlan Cox
When we close we must clear the extra reference we got when we read port->tty. Setting the port tty NULL will clear the kref held by the driver but not the one we obtained ourselves while doing the lookup.

2008-10-29USB: prevent autosuspend during hub initializationAlan Stern
This patch (as1153) fixes a potential problem in hub initialization. Starting in 2.6.28, initialization was split into several tasks to help speed up booting. This opens the possibility that the hub may be autosuspended before all the initialization tasks can complete. Normally that wouldn't matter, but with incomplete initialization there is a risk that the hub would never autoresume -- especially if devices were plugged into the hub beforehand. The solution is a simple one-line change to suppress autosuspend until the initialization is finished.

2008-10-29USB: fix crash when URBs are unlinked after the device is goneAlan Stern
This patch (as1151) protects usbcore against drivers that try to unlink an URB after the URB's device or bus have been removed. The core does not currently check for this, and certain drivers can cause a crash if they are running while an HCD is unloaded. Certainly it would be best to fix the guilty drivers. But a little defensive programming doesn't hurt, especially since it appears that quite a few drivers need to be fixed. The patch prevents the problem by grabbing a reference to the device while an unlink is in progress and using a new spinlock to synchronize unlinks with device removal. (There's no need to acquire a reference to the bus as well, since the device structure itself keeps a reference to the bus.) In addition, the kerneldoc is updated to indicate that URBs should not be unlinked after the disconnect method returns.

2008-10-22USB: don't rebind drivers after failed resume or resetAlan Stern
This patch (as1152) may help prevent some problems associated with the new policy of unbinding drivers that don't support suspend/resume or pre_reset/post_reset. If for any reason the resume or reset fails, and the device is logically disconnected, there's no point in trying to rebind the driver. So the patch checks for success before carrying out the unbind/rebind. There was a report from one user that this fixed a problem he was experiencing, but the details never became fully clear. In any case, adding these tests can't hurt. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

So to declare the unusual device for new Huawei data card devices in unusual_devs.h and to declare more new product IDs in option.c. To modify the data value and length in the function of usb_stor_huawei_e220_init in initializers.c That's because based on the USB standard, while sending SET_FETURE_D to the device, it requires the corresponding data to be zero, and its sending length also must be zero.

2008-10-17USB: OHCI: fix endless polling behaviorAlan Stern
This patch (as1149) fixes an obscure problem in OHCI polling. In the current code, if the RHSC interrupt status flag turns on at a time when RHSC interrupts are disabled, it will remain on forever: The interrupt handler is the only place where RHSC status gets turned back off; The interrupt handler won't turn RHSC status off because it doesn't turn off status flags if the corresponding interrupt isn't enabled; RHSC interrupts will never get enabled because ohci_root_hub_state_changes() doesn't reenable RHSC if RHSC status is on! As a result we will continue polling indefinitely instead of reverting to interrupt-driven operation, and the root hub will not autosuspend. This particular sequence of events is not at all unusual; in fact plugging a USB device into an OHCI controller will usually cause it to occur. Of course, this is a bug. The proper thing to do is to turn off RHSC status just before reading the actual port status values. That way either a port status change will be detected (if it occurs before the status read) or it will turn RHSC back on. Possibly both, but that won't hurt anything. We can still check for systems in which RHSC is totally broken, by re-reading RHSC after clearing it and before reading the port statuses. (This re-read has to be done anyway, to post the earlier write.) If RHSC is on but no port-change statuses are set, then we know that RHSC is broken and we can avoid re-enabling it.

These controllers turn off the RESUME bit by themselves when a port resume is complete; hence we need to keep separate track of which ports are suspended or in the process of resuming.
