2017-07-22usb: core: hub: controller driver name may be NULLPeter Chen
The controller driver may be NULL if the controller device is the middle device between platform device and roothub. This middle device may not need a device driver due to all hardware control can be at platform device driver, this platform device is usually a dual-role USB controller device. The benefit of using this middle device is we can keep both controller device's private data (known as struct usb_hcd) for USB core use, and platform device's private data for platform driver use.

2017-07-20xhci: fix 20000ms port resume timeoutMathias Nyman
A uncleared PLC (port link change) bit will prevent furuther port event interrupts for that port. Leaving it uncleared caused get_port_status() to timeout after 20000ms while waiting to get the final port event interrupt for resume -> U0 state change. This is a targeted fix for a specific case where we get a port resume event racing with xhci resume. The port event interrupt handler notices xHC is not yet running and bails out early, leaving PLC uncleared. The whole xhci port resuming needs more attention, but while working on it it anyways makes sense to always ensure PLC is cleared in get_port_status before setting a new link state and waiting for its completion.

2017-07-20usb: xhci: Issue stop EP command only when the EP state is runningShyam Sundar S K
on AMD platforms with SNPS 3.1 USB controller if stop endpoint command is issued the controller does not respond, when the EP is not in running state. HW completes the command execution and reports "Context State Error" completion code. This is as per the spec. However HW on receiving the second command additionally marks EP to Flow control state in HW which is RTL bug. This bug causes the HW not to respond to any further doorbells that are rung by the driver. This makes the EP to not functional anymore and causes gross functional failures. As a workaround, not to hit this problem, it's better to check the EP state and issue a stop EP command only when the EP is in running state. As a sidenote, even with this patch there is still a possibility of triggering the RTL bug if the context state races with the stop endpoint command as described in xHCI spec 4.6.9 [code simplification and reworded sidenote in commit message -Mathias] Signed-off-by: Shyam Sundar S K <Shyam-sundar.S-k@amd.com> Signed-off-by: Nehal Shah <Nehal-bakulchandra.Shah@amd.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This off by one in stream_id indexing caused NULL pointer dereference and soft lockup on machines with USB attached SCSI devices connected to a hotpluggable xhci controller. The code that cleans up pending URBs for dead hosts tried to dereference a stream ring at the invalid stream_id 0. ep->stream_info->stream_rings[0] doesn't point to a ring. Start looping stream_id from 1 like in all the other places in the driver, and check that the ring exists before trying to kill URBs on it.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v4.13-rc2 First set of fixes for the current -rc cycle. Only three fixes on dwc3 this time around (proper order for getting a PHY reference, fix for unmapping DMA and a fix for requesting IRQ on the OMAP glue layer). Most fixes are on the renesas USB controller, fixing several old bugs with most going to stable. dwc2 also learned that it *must* reset USB Address to zero on Reset interrupts. Apart from these, some drivers needed HAS_DMA dependency and there's a sparse warning fix for bdc udc.
2017-07-19usb: renesas_usbhs: gadget: disable all eps when the driver stopsYoshihiro Shimoda
A gadget driver will not disable eps immediately when ->disconnect() is called. But, since this driver assumes all eps stop after the ->disconnect(), unexpected behavior happens (especially in system suspend). So, this patch disables all eps in usbhsg_try_stop(). After disabling eps by renesas_usbhs driver, since some functions will be called by both a gadget and renesas_usbhs driver, renesas_usbhs driver should protect uep->pipe. To protect uep->pipe easily, this patch adds a new lock in struct usbhsg_uep.

2017-07-17usb: dwc3: gadget: only unmap requests from DMA if mappedJack Pham
A recent optimization was made so that a request put on the pending_list wouldn't get mapped for DMA until just before preparing a TRB for it. However, this poses a problem in case the request is dequeued or the endpoint is disabled before the mapping is done as that would lead to dwc3_gadget_giveback() unconditionally calling usb_gadget_unmap_request_for_dev() with an invalid request->dma handle. Depending on the platform's DMA implementation the unmap operation could result in a panic. Since we know a successful mapping is a prerequisite for getting a TRB, the unmap can be conditionally called only when req->trb is non-NULL.

IRQ_NOAUTOEN cannot be used with shared IRQs, since commit 04c848d39879 ("genirq: Warn when IRQ_NOAUTOEN is used with shared interrupts") and kernel now throws a warn dump. But OMAP DWC3 driver uses this flag. As per commit 12a7f17fac5b ("usb: dwc3: omap: fix race of pm runtime with irq handler in probe") that introduced this flag, PM runtime can race with IRQ handler when deferred probing happens due to extcon, therefore IRQ_NOAUTOEN needs to be set so that irq is not enabled until extcon is registered. Remove setting of IRQ_NOAUTOEN and move the registration of shared irq to a point after dwc3_omap_extcon_register() and of_platform_populate(). This avoids possibility of probe deferring and above said race condition.

2017-07-17usb: dwc3: core: Call dwc3_core_get_phy() before initializing physVignesh R
commit f54edb539c116 ("usb: dwc3: core: initialize ULPI before trying to get the PHY") moved call to dwc3_core_get_phy() from dwc3_probe() to dwc3_core_init() after dwc3_core_soft_reset(). But dwc3_core_soft_reset() calls phy_init(), therefore dwc3_core_get_phy() needs to be called before dwc3_core_soft_reset(). Fix this by moving call to dwc3_core_get_phy() before dwc3_core_soft_reset().

Not all compat syscalls are gone from it yet, but it's getting there. - ipc/compat_mq.c killed off completely. - block/compat_ioctl.c cleaned up; floppy compat ioctls moved to drivers/block/floppy.c where they belong. Yes, there are several drivers that implement some of the same ioctls.
