usb: gadget: udc: renesas_usb3: fix oops in renesas_usb3_remove()

2018-03-21T11:05:47Z

commit e3190868e5f52fb26544f16463593d54ce46ce61 upstream. This patch fixes an issue that the renesas_usb3_remove() causes NULL pointer dereference because the usb3_to_dev() macro will use the gadget instance and it will be deleted before.

usb: dwc3: of-simple: fix oops by unbalanced clk disable call

2018-03-21T11:05:47Z

commit bff52352e0ccc2481f2b6b0d612ff8ff56c50f3a upstream. dwc3_of_simple_dev_pm_ops has never been used since commit a0d8c4cfdf31 ("usb: dwc3: of-simple: set dev_pm_ops"), but this commit has brought and oops when unbind the device due this sequence: dwc3_of_simple_remove -> clk_disable ... -> pm_runtime_put_sync -> dwc3_of_simple_runtime_suspend -> clk_disable (again) This double call to clk_core_disable causes a kernel oops like this: WARNING: CPU: 1 PID: 4022 at drivers/clk/clk.c:656 clk_core_disable+0x78/0x80 CPU: 1 PID: 4022 Comm: bash Not tainted 4.15.0-rc4+ #44 Hardware name: Google Kevin (DT) pstate: 80000085 (Nzcv daIf -PAN -UAO) pc : clk_core_disable+0x78/0x80 lr : clk_core_disable_lock+0x20/0x38 sp : ffff00000bbf3a90 ...

usb: dwc3: core: Power-off core/PHYs on system_suspend in host mode

2018-03-21T11:05:47Z

commit c4a5153e87fdf6805f63ff57556260e2554155a5 upstream. Commit 689bf72c6e0d ("usb: dwc3: Don't reinitialize core during host bus-suspend/resume") updated suspend/resume routines to not power_off and reinit PHYs/core for host mode. It broke platforms that rely on DWC3 core to power_off PHYs to enter low power state on system suspend. Perform dwc3_core_exit/init only during host mode system_suspend/ resume to addresses power regression from above mentioned patch and also allow USB session to stay connected across runtime_suspend/resume in host mode. While at it also replace existing checks for HOST only dr_mode with current_dr_role to have similar core driver behavior for both Host-only and DRD+Host configurations.

2018-03-21T11:05:47Z

commit b16ea8b9492e99e03b1269fe93ebdbf8e4eabf8a upstream. The FIFO/Queue type values are incorrect. Correct them according to DWC_usb3 programming guide section 1.2.27 (or DWC_usb31 section 1.2.25). Additionally, this patch includes ProtocolStatusQ and AuxEventQ types.

USB: ledtrig-usbport: fix of-node leak

2018-03-19T08:09:51Z

[ Upstream commit 03310a15484ab6a8f6d91bbf7fe486b17275c09a ] This code looks up a USB device node from a given parent USB device but never dropped its reference to the returned node. As only the address of the node is used for a later matching, the reference can be dropped immediately. Note that this trigger implementation confuses the description of the USB device connected to a port with the port itself (which does not have a device-tree representation).
