| * | usb: gadgetfs: Convert semaphore to mutexThomas Gleixner2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The semaphore data->lock is semantically a mutex. Convert it to a real mutex. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
| * | USB: g_mass_storage: superfluous and missing packets fixedMichal Nazarewicz2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mass storage function responded needlessly to a set configuration packet. This was a leftover from converting gadget (file storage gadget) into a composite function. Moreover, it has failed to respond to get max LUN request. Adding request queueing made the function work better.

| * | USB: mass_storage: eject LUNs on thread exitMichal Nazarewicz2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All current Blackfin parts are using RTL v1.9, but they don't expose the hardware registers to probe this dynamically.

| * | USB: pxa27x_udc: Fix deadlocks on request queueingRobert Jarzmik2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | USB: serial: add support for serial port on the moschip 7715Mike Dunn2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the serial port on devices based on the MosChip 7715, which provides a serial and parallel port on a single usb interface. This is added to the existing driver for the Moschip 7720 dual serial port device. The 7715 is very similiar to the 7720, requiring only the addition of a calc_num_ports() function, a separate interrupt-in endpoint callback, and some manipulation of the port pointers added to the attach() function to correct the fact that the usbserial core erroneously assigns the first bulk in/out endpoint pair to the serial port (the 7715 uses these for its parallel port). There is no support for the 7715's parallel port yet. Signed-off-by: Mike Dunn <mikedunn@newsguy.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Johan Hovold points out that get_string() is basically just a re-implimentation of usb_string(). It is also buggy. It does DMA on the stack and it doesn't handle negative returns from usb_get_descriptor(). Plus unicode_to_ascii() is a rubbish function and moving to usb_string() avoids using it. Let's eliminate get_string() entirely.

The blacklisting code is heavily stolen from sierra.c, but extended to support different special cases. For now, one case is implemented (OPTION_BLACKLIST_SENDSETUP), targeted at the 4G W14 device: devices which don't understand the setting of RTS/DTR in option_send_setup() causing a USB timeout of 5 s in any userspace open() which leads to errors in most userspace applications. In addition, I prepared another case for devices with interfaces which shall not be accessed by this driver (targeted at the D-Link DWM 652). However, OPTION_BLACKLIST_RESERVED_IF is not fully implemented yet as I have no device to test this. Anyone volunteering to help here? If not, I'll contact the guys who added D-Link DWM 652 support soon. Signed-off-by: Gernot Hillier <gernot@hillier.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
