2014-01-04USB: pl2303: fix data corruption on termios updatesJohan Hovold1-9/+25
Some PL2303 devices are known to lose bytes if you change serial settings even to the same values as before. Avoid this by comparing the encoded settings with the previsouly used ones before configuring the device. The common case was fixed by commit bf5e5834bffc6 ("pl2303: Fix mode switching regression"), but this problem was still possible to trigger, for instance, by using the TCSETS2-interface to repeatedly request 115201 baud, which gets mapped to 115200 and thus always triggers a settings update.

Because of that, we describe the changes in sections below: New drivers: - Keystone PHY driver and DWC3 Glue Layer - Aeroflex Gaisler GRUSBDC - Tahvo PHY driver for N770 - JZ4740 MUSB gluer Layer - Broadcom PHY Driver Important new features: - MUSB DSPS learned about suspend/resume - New quirk_ep_out_aligned_size flag added to struct usb_gadget - DWC3 initializes the new quirk flag so gadget drivers can use it. - AM335x PHY Driver learns about remote wakeup - Renesas USBHS now requests DMA Engine only once - s3c-hsotg is now re-used on Broadcom devices - USB PHY layer now makes sure to initialize the notifier for all drivers - omap-control learned about TI's new AM437x devices - few other usb gadget/function drivers learned about the new configfs-based binding. Misc Fixes and Clean Ups: - Several sparse fixes all over the place - Removal of redundant of_match_ptr() - r-car gen2 phy now uses usb_add_phy_dev() - removal of DEFINE_PCI_DEVICE_TABLE() from a few drivers - conversion to clk_prepare/clk_unprepare on r8a66597-udc - some randconfig errors and build warnings were fixed - removal of unnecessary lock on dwc3-omap.c Signed-of-by: Felipe Balbi <balbi@ti.com>

2013-12-22USB: core: remove CONFIG_USB_DEBUG usageGreg Kroah-Hartman3-18/+7
CONFIG_USB_DEBUG is going away, so remove the few places in the USB core that relied on them. This means that we always now do the "debug" checks for every urb submitted, which is a good idea, as who knows how many driver bugs we have been ignoring when people forget to enable this option. Also, with the overall speed of USB, doing these extra checks should not cause any additional overhead. Also, no longer announce all devices being added to the system if CONFIG_USB_DEBUG is enabled, as it's not going to be around much longer.

git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-next Sarah writes: xhci: Cleanups, non-urgent fixes for 3.14. Happy Holidays, Greg! Here's four patches to be queued to usb-next for 3.14. One adds a module parameter to the xHCI driver to allow users to enable xHCI quirks without recompiling their kernel, which you've already said is fine. The second patch is a bug fix for new usbtest code that's only in usb-next. The third patch is simple cleanup. The last patch is a non-urgent bug fix for xHCI platform devices. The bug has been in the code since 3.9. You've been asking me to hold off on non-urgent bug fixes after -rc4/-rc5, so it can go into usb-next, and be backported to stable once 3.14 is out. These have all been tested over the past week. I did run across one oops, but it turned out to be a bug in 3.12, and therefore not related to any of these patches. Please queue these for usb-next and 3.14. Thanks, Sarah Sharp

2013-12-21uwb: move mutex_lock to error case in uwbd_evt_handle_rc_bp_slot_changeThomas Pugliese1-2/+2
Only acquire rc->uwb_dev.mutex in the error case in uwbd_evt_handle_rc_bp_slot_change. This fixes a bug where establishing a reservation on a new channel will fail if we were unable to establish a reservation on the previous channel due to DRP conflict. If rc->uwb_dev.mutex is acquired in the non-error case when the uwb system is attempting to start beaconing, it will block because the start beaconing code is holding this mutex. This prevents any other notifications from the URC from being processed. In particular, the DRP_AVAILABILITY notification will not be processed during the start beaconing process which can result in a failure to establish a reservation. It is safe to not hold the mutex in the non-error case since the only other place rc->uwb_dev.beacon_slot is accessed is in the same worker thread that uwbd_evt_handle_rc_bp_slot_change executes in.

2013-12-21usb: cdc-wdm: avoid hanging on zero length readsBjørn Mork1-32/+38
commit 73e06865ead1 ("USB: cdc-wdm: support back-to-back USB_CDC_NOTIFY_RESPONSE_AVAILABLE notifications") implemented queued response handling. This added a new requirement: The read urb must be resubmitted every time we clear the WDM_READ flag if the response counter indicates that the device is waiting for a read. Fix by factoring out the code handling the WMD_READ clearing and possible urb submission, calling it everywhere we clear the flag. Without this fix, the driver ends up in a state where the read urb is inactive, but the response counter is positive after a zero length read. This prevents the read urb from ever being submitted again and the driver appears to be hanging.

2013-12-20usb: musb: fix setting JZ4740 gadget periphal mode on resetApelete Seketeli1-1/+9
JZ4740 USB Device Controller is not OTG compatible and does not have DEVCTL register in silicon. During ethernet-over-usb transactions, on reset, musb driver tries to read from DEVCTL and consequently sets device as host (A-Device) instead of peripheral (B-Device), which makes it a composite device to the USB gadget driver. This induces a kernel panic during power down where the USB gadget driver does a null pointer dereference when trying to access the composite device configuration. On reset, do not rely on DEVCTL value for setting gadget peripheral mode. Use is_otg flag instead to set it to B-Device.

2013-12-20usb: gadget: fix up some comments about CONFIG_USB_DEBUGGreg Kroah-Hartman2-2/+2
These two gadget drivers said that their #endif was for CONFIG_USB_DEBUG, but they really were not, so fix them up to be correct. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-12-20qla2xxx: Fix scsi_host leak on qlt_lport_register callback failureNicholas Bellinger1-0/+1
This patch fixes a possible scsi_host reference leak in qlt_lport_register(), when a non zero return from the passed (*callback) does not call drop the local reference via scsi_host_put() before returning. This currently does not effect existing tcm_qla2xxx code as the passed callback will never fail, but fix this up regardless for future code.

2013-12-20target: Remove extra percpu_ref_initAndy Grover1-7/+1
lun->lun_ref is also initialized in core_tpg_post_addlun, so it doesn't need to be done in core_tpg_setup_virtual_lun0. (nab: Drop left-over percpu_ref_cancel_init in failure path) Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2013-12-20usb: xhci: Check for XHCI_PLAT in xhci_cleanup_msix()Jack Pham1-0/+3
If CONFIG_PCI is enabled, make sure xhci_cleanup_msix() doesn't try to free a bogus PCI IRQ or dereference an invalid pci_dev when the xHCI device is actually a platform_device. This patch should be backported to kernels as old as 3.9, that contain the commit 52fb61250a7a132b0cfb9f4a1060a1f3c49e5a25 "xhci-plat: Don't enable legacy PCI interrupts."
