usb: ldusb: add PIDs for new CASSY devices supported by this driver

2018-03-04T15:28:34+00:00

[ Upstream commit 52ad2bd8918158266fc88a05f95429b56b6a33c5 ]

This patch adds support for new CASSY devices to the ldusb driver. The
PIDs are also added to the ignore list in hid-quirks.

usb: misc: usb3503: make sure reset is low for at least 100us

2018-03-01T03:09:36+00:00

[ Upstream commit b8626f1dc29d3eee444bfaa92146ec7b291ef41c ]

When using a GPIO which is high by default, and initialize the
driver in USB Hub mode, initialization fails with:
  [  111.757794] usb3503 0-0008: SP_ILOCK failed (-5)

The reason seems to be that the chip is not properly reset.
Probe does initialize reset low, however some lines later the
code already set it back high, which is not long enouth.

Make sure reset is asserted for at least 100us by inserting a
delay after initializing the reset pin during probe.

usb: usbtest: fix NULL pointer dereference

2017-12-07T02:20:05+00:00

[ Upstream commit 7c80f9e4a588f1925b07134bb2e3689335f6c6d8 ]

If the usbtest driver encounters a device with an IN bulk endpoint but
no OUT bulk endpoint, it will try to dereference a NULL pointer
(out->desc.bEndpointAddress).  The problem can be solved by adding a
missing test.

USB: iowarrior: fix info ioctl on big-endian hosts

[ Upstream commit dd5ca753fa92fb736b1395db892bd29f78e6d408 ]

Drop erroneous le16_to_cpu when returning the USB device speed which is
already in host byte order.

Found using sparse:

	warning: cast to restricted __le16

USB: uss720: fix NULL-deref at probe

2017-05-17T19:07:01+00:00

[ Upstream commit f259ca3eed6e4b79ac3d5c5c9fb259fb46e86217 ]

Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer or accessing memory beyond the endpoint array should a
malicious device lack the expected endpoints.

Note that the endpoint access that causes the NULL-deref is currently
only used for debugging purposes during probe so the oops only happens
when dynamic debugging is enabled. This means the driver could be
rewritten to continue to accept device with only two endpoints, should
such devices exist.

Make sure to check the number of endpoints to avoid dereferencing a

Note that this driver does not bind to any devices by default.

USB: iowarrior: fix NULL-deref at probe

[ Upstream commit b7321e81fc369abe353cf094d4f0dc2fe11ab95f ]

Make sure to check for the required interrupt-in endpoint to avoid
dereferencing a NULL-pointer should a malicious device lack such an
endpoint.

Note that a fairly recent change purported to fix this issue, but added
an insufficient test on the number of endpoints only, a test which can
now be removed.
