2015-10-04usb: Add device quirk for Logitech PTZ camerasVincent Palatin
Add a device quirk for the Logitech PTZ Pro Camera and its sibling the ConferenceCam CC3000e Camera. This fixes the failed camera enumeration on some boot, particularly on machines with fast CPU. Tested by connecting a Logitech PTZ Pro Camera to a machine with a Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles while recording the kernel logs and taking camera picture after each boot. Before the patch, more than 7% of the boots show some enumeration transfer failures and in a few of them, the kernel is giving up before actually enumerating the webcam. After the patch, the enumeration has been correct on every reboot.

This patch adds a compatible string to support for R-Car H3. Since the HS-USB controller of R-Car H3 is almost the same specification with R-Car Gen2 (these have 16 pipes and usb-dmac), this patch sets the "type" of renesas_usbhs_driver_param to USBHS_TYPE_RCAR_GEN2.

2015-09-23USB: whiteheat: fix potential null-deref at probeJohan Hovold
Fix potential null-pointer dereference at probe by making sure that the required endpoints are present. The whiteheat driver assumes there are at least five pairs of bulk endpoints, of which the final pair is used for the "command port". An attempt to bind to an interface with fewer bulk endpoints would currently lead to an oops. Fixes CVE-2015-5257.

Bits 1:0 of the bmAttributes are used for the burst multiplier. The rest of the bits used to be reserved (zero), but USB3.1 takes bit 7 into use. Use the existing USB_SS_MULT() macro instead to make sure the mult value and hence max packet calculations are correct for USB3.1 devices. Note that burst multiplier in bmAttributes is zero based and that the USB_SS_MULT() macro adds one.

2015-09-15usb: chipidea: udc: using the correct stall implementationPeter Chen
According to spec, there are functional and protocol stalls. For functional stall, it is for bulk and interrupt endpoints, below are cases for it: - Host sends SET_FEATURE request for Set-Halt, the udc driver needs to set stall, and return true unconditionally. - The gadget driver may call usb_ep_set_halt to stall certain endpoints, if there is a transfer in pending, the udc driver should not set stall, and return -EAGAIN accordingly. These two kinds of stall need to be cleared by host using CLEAR_FEATURE request (Clear-Halt). For protocol stall, it is for control endpoint, this stall will be set if the control request has failed. This stall will be cleared by next setup request (hardware will do it). It fixed usbtest (drivers/usb/misc/usbtest.c) Test 13 "set/clear halt" test failure, meanwhile, this change has been verified by USB2 CV Compliance Test and MSC Tests.

2015-09-14usb: musb: ensure in peripheral mode when checking sessionBin Liu
The change ensures otg is not in a A- state when checking for VBUS in peripheral mode. musb_start() where VBUS checking is in can be called in many situations. One example is in babble recovery routine, in which otg is transitioning from A-HOST to A-WAIT-BCON, but VBUS discharge takes time, so musb->is_active could be set to 1 due to this improper checking, then it causes musb_bus_suspend() failed which leads to warning log message flooding.

This patch fixes possible regression introduced by patch reworking endpoint claiming mechanism. It restores setring ep->driver_data to NULL in usb_ep_autoconfig_reset(), which was removed by patch commit cc476b42a39d.

2015-08-18USB: symbolserial: Correct transferred data sizePhilipp Hachtmann
The scanner (here DS3508) always returns 64 bytes per urb buffer. The first byte indicates the data length used in the current buffer. There even was a comment describing this. But the comment also said that we'll send everything in the buffer to the tty layer. That means sending the actual barcode data and lots of trailing zeroes. This patch lets the driver only send the real data.
