2009-04-06symbol: Remove various bits of left over junkAlan Cox
There are various bits of code here that are unfinished and instead of being harmless either confuse or spew stuff into the logs at higher than debug level. They can and should go away. Also remove the bogus use of tty->lowlatency. We fixed the need for this hack long ago (with the flip buffer rewrite) but people keep copying it into drivers.

2009-04-02workqueue: add to_delayed_work() helper functionJean Delvare
It is a fairly common operation to have a pointer to a work and to need a pointer to the delayed work it is contained in. In particular, all delayed works which want to rearm themselves will have to do that. So it would seem fair to offer a helper function for this operation.

Use the new device-level suspend/resume hooks for Gadget Zero; always enable them with the OTG test mode; and support remote wakeup on both configurations even in non-OTG mode. This ensures that both configurations can pass the USBCV remote wakeup tests when the OTG test mode is enabled. This changes behavior by adding autoresume support to the loopback config even in non-OTG mode; the test failure was that it didn't work in OTG mode.

2009-03-24USB: more u32 conversion after transfer_buffer_length and actual_lengthRoel Kluin

A test for a negative urb->transfer_buffer_length became obsolete; instead we ensure that it does not exceed INT_MAX. Also, urb->actual_length is always less than urb->transfer_buffer_length. rh_string() does no longer return -EPIPE in the case of an unsupported ID. Instead its only caller, rh_call_control() does the check.

2009-03-24USB: don't send Set-Interface after resetAlan Stern
This patch (as1221) changes the way usbcore reinitializes a device following a reset or a reset-resume. Currently we call usb_set_interface() for every interface in the active configuration; this is to put the interface into the same altsetting as before the reset and to make sure that the host's endpoint state matches the device's endpoint state. However, sending a Set-Interface request is a waste of time if an interface was already in altsetting 0 before the reset, since it is certainly in altsetting 0 afterward. In addition, many devices can't handle Set-Interface requests -- they crash when they receive them. So instead, the patch adds code to check each interface. If the interface wasn't in altsetting 0 before the reset, we go head with the Set-Interface request as before. But if it was then we skip sending the Set-Interface request, and we clear out the host-side endpoint state by calling usb_disable_interface() followed by usb_enable_interface(). The patch also adds a couple of new comments to explain what's going on. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
