usb: typec: fusb302: fix "op-sink-microwatt" default that was in mW

2020-02-01T09:32:53+00:00

commit eb7a3bb8c955b3694e0e0998413ce1563c02f90c upstream.

commit 8f6244055bd3 ("usb: typec: fusb302: Always provide fwnode for the
port") didn't convert this value from mW to uW when migrating to a new
specification format like it should have.

usb: dwc3: turn off VBUS when leaving host mode

commit 09ed259fac621634d51cd986aa8d65f035662658 upstream.

VBUS should be turned off when leaving the host mode.
Set GCTL_PRTCAP to device mode in teardown to de-assert DRVVBUS pin to
turn off VBUS power.

USB: serial: ir-usb: fix IrLAP framing

2020-02-01T09:32:52+00:00

commit 38c0d5bdf4973f9f5a888166e9d3e9ed0d32057a upstream.

Commit f4a4cbb2047e ("USB: ir-usb: reimplement using generic framework")
switched to using the generic write implementation which may combine
multiple write requests into larger transfers. This can break the IrLAP
protocol where end-of-frame is determined using the USB short packet
mechanism, for example, if multiple frames are sent in rapid succession.

USB: serial: ir-usb: fix link-speed handling

2020-02-01T09:32:52+00:00

commit 17a0184ca17e288decdca8b2841531e34d49285f upstream.

Commit e0d795e4f36c ("usb: irda: cleanup on ir-usb module") added a USB
IrDA header with common defines, but mistakingly switched to using the
class-descriptor baud-rate bitmask values for the outbound header.

This broke link-speed handling for rates above 9600 baud, but a device
would also be able to operate at the default 9600 baud until a
link-speed request was issued (e.g. using the TCGETS ioctl).

USB: serial: ir-usb: add missing endpoint sanity check

2020-02-01T09:32:52+00:00

commit 2988a8ae7476fe9535ab620320790d1714bdad1d upstream.

Add missing endpoint sanity check to avoid dereferencing a NULL-pointer
on open() in case a device lacks a bulk-out endpoint.

Note that prior to commit f4a4cbb2047e ("USB: ir-usb: reimplement using
generic framework") the oops would instead happen on open() if the
device lacked a bulk-in endpoint and on write() if it lacked a bulk-out
endpoint.

Merge tag 'usb-serial-5.5-rc7' of https://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial into usb-linus

USB-serial fixes for 5.5-rc7

Here are a few fixes for issues related to unbound port devices which
could lead to NULL-pointer dereferences. Notably the bind attributes for
usb-serial (port) drivers are removed as almost none of the drivers can
handle individual ports going away once they've been bound.

Included are also some new device ids.

All but the unbound-port fixes have been in linux-next with no reported
issues.

2020-01-17T15:22:59+00:00

Check for NULL port data in the modem- and line-status handlers to avoid
dereferencing a NULL pointer in the unlikely case where a port device
isn't bound to a driver (e.g. after an allocation failure on port
probe).

Note that the other (stubbed) event handlers qt2_process_xmit_empty()
and qt2_process_flush() would need similar sanity checks in case they
are ever implemented.
