2014-11-24storage: Fix bus scan and multi-LUN support for SCM eUSCSI devicesMark Knibbs
This patch does two things for SCM eUSCSI USB-SCSI converters: 1. SCM eUSCSI bridge devices are hard-wired to use SCSI ID 7. On connecting the converter, access to that ID is attempted during the bus scan. Asking the converter to issue INQUIRY commands to itself isn't very polite and wastes time. Set this_id to 7 so __scsi_scan_target() skips it in the scan. 2. Enable multi-LUN support. eUSCSI devices don't support Get Max LUN requests, returning an error (-32). [Different targets could have different numbers of LUNs, so it wouldn't make sense to return a particular value in response to Get Max LUN.] usb_stor_scan_dwork() does this: /* For bulk-only devices, determine the max LUN value */ if (us->protocol == USB_PR_BULK && !(us->fflags & US_FL_SINGLE_LUN)) { mutex_lock(&us->dev_mutex); us->max_lun = usb_stor_Bulk_max_lun(us); mutex_unlock(&us->dev_mutex); It avoids calling usb_stor_Bulk_max_lun() if US_FL_SINGLE_LUN, but not for US_FL_SCM_MULT_TARG. Since usb_stor_Bulk_max_lun() returns 0 in the error case, us->max_lun was always set to 0. [If the user doesn't want multi-LUN support (perhaps there are SCSI devices which respond to commands on all LUNs?), the US_FL_SINGLE_LUN quirk can be specified on the kernel command line.] Signed-off-by: Mark Knibbs <markk@clara.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Otherwise, some platforms may generate spurious wakeup, even if PCI PME# is disabled.

2014-11-22USB: xhci: Reset a halted endpoint immediately when we encounter a stall.Mathias Nyman
If a device is halted and reuturns a STALL, then the halted endpoint needs to be cleared both on the host and device side. The host side halt is cleared by issueing a xhci reset endpoint command. The device side is cleared with a ClearFeature(ENDPOINT_HALT) request, which should be issued by the device driver if a URB reruen -EPIPE. Previously we cleared the host side halt after the device side was cleared. To make sure the host side halt is cleared in time we want to issue the reset endpoint command immedialtely when a STALL status is encountered. Otherwise we end up not following the specs and not returning -EPIPE several times in a row when trying to transfer data to a halted endpoint.

2014-11-22USB: xhci: don't start a halted endpoint before its new dequeue is setMathias Nyman
A halted endpoint ring must first be reset, then move the ring dequeue pointer past the problematic TRB. If we start the ring too early after reset, but before moving the dequeue pointer we will end up executing the same problematic TRB again. As we always issue a set transfer dequeue command after a reset endpoint command we can skip starting endpoint rings at reset endpoint command completion. Without this fix we end up trying to handle the same faulty TD for contol endpoints. causing timeout, and failing testusb ctrl_out write tests.

This patch adds a call to s3c_hsotg_disconnect() from 'end session' interrupt (GOTGINT_SES_END_DET) to correctly notify gadget subsystem about unplugged usb cable. DISCONNINT interrupt cannot be used for this purpose, because it is asserted only in host mode. To avoid reporting disconnect event more than once, a disconnect call has been moved from USB_REQ_SET_ADDRESS handling function to SESSREQINT interrupt. This way driver ensures that disconnect event is reported either when usb cable is unplugged or every time the host starts a new session. To handle devices which has been synthesized without SRP support, connected state is set in ENUMDONE interrupt.
