2010-03-29ARM: 5965/1: Fix soft lockup in at91 udc driverHarro Haan
Fix a potential soft lockup in the AT91 UDC driver by ensuring that the UDC clock is enabled inside the interrupt handler. If the UDC clock is not enabled then the UDC registers cannot be written to and the interrupt cannot be cleared or masked. Note that this patch (and other parts of the existing AT91 UDC driver) is potentially racy for preempt-rt kernels, but is okay for mainline.

The recent commit (0e530b45783f75) that moved usb_ep_autoconfig from the __devinit section to the __init section missed the mass storage device.

2010-03-02USB: mass_storage: eject LUNs on thread exitMichal Nazarewicz
Adds a fallback which forces all LUNs ejection (including non-removable and with prevent_medium_removal flag) when mass storage function (MSF) worker thread exits and gadget fails to handle the situation. Previously, if thread_exits was not specified mass storage function (MSF) did nothing when exiting thread as it's unclear for *function* what to do when it's thread terminates so responsibility of handling this situation was left to the *gadget* using the function. The g_mass_storage handled the situation by unregistering itself (the same thing that file storage gadget does). However, g_multi did nothing and so MSF did not eject LUNs which prevented file system unmounting.

2010-03-02USB: pxa27x_udc: Fix deadlocks on request queueingRobert Jarzmik
As reported by Antonio, there are cases where the ep->lock can be taken twice, triggering a deadlock. The typical sequence is : irq_handler \ -> gadget.complete() \ -> pxa27x_udc.pxa_ep_queue() : ep->lock is taken \ -> gadget.complete() \ -> pxa27x_udc.pxa_ep_queue() : ep->lock is taken ==> *deadlock* The patch fixes this by : - releasing the lock each time gadget.complete() is called - adding a check in handle_ep() to detect a recursive call, in which case the function becomes on no-op. The patch is still not good enough for ep0. For this unique endpoint, another well thought over patch will be needed.

Normally, the musb uses ep1 as the bidirectional bulk endpoint. This won't work on the Blackfin musb as all endpoints (except ep0) are unidirectional. Further, ep1-ep4 have a small 128 byte FIFO which makes them undesirable for bulk endpoints (which need more like a 512 byte FIFO). This leaves us with ep5-ep7 which have 1024 byte FIFOs and can be configured as either in/out and bulk/interrupt/iso on the fly.
