commit f0797095423e6ea3b4be61134ee353c7f504d440 upstream.

These are the Foxconn-branded variants of the Dell DW5821e modules,
same USB layout as those. The device exposes AT, NMEA and DIAG ports
in both USB configurations.

Exactly same layout as the default DW5821e module, just a different
vid/pid.

commit 92fe35fb9c70a00d8fbbf5bd6172c921dd9c7815 upstream.

The driver was setting the device remote-wakeup feature during probe in
violation of the USB specification (which says it should only be set
just prior to suspending the device). This could potentially waste
power during suspend as well as lead to spurious wakeups.

Note that USB core would clear the remote-wakeup feature at first
resume.

Add USB ID for MOXA UPort 2210. This device contains mos7820 but
it passes GPIO0 check implemented by driver and it's detected as
mos7840. Hence product id check is added to force mos7820 mode.

commit 91feb01596e5efc0cc922cc73f5583114dccf4d2 upstream.

The work item can operate on

1. stale memory left over from the last transfer
the actual length of the data transfered needs to be checked
2. memory already freed
the error handling in appledisplay_probe() needs
to cancel the work in that case

commit 92aa5986f4f7b5a8bf282ca0f50967f4326559f5 upstream.

In case of a timeout or if a signal aborts a read
communication with the device needs to be ended
lest we overwrite an active URB the next time we
do IO to the device, as the URB may still be active.

commit 347bc8cb26388791c5881a3775cb14a3f765a674 upstream.

Add support for the Mark-10 digital force gauge device to the cp201x
driver.

Based on a report and a larger patch from Joel Jennings

<title>usbip: Fix uninitialized symbol 'nents' in stub_recv_cmd_submit()</title>

commit 2a9125317b247f2cf35c196f968906dcf062ae2d upstream.

Smatch reported that nents is not initialized and used in
stub_recv_cmd_submit(). nents is currently initialized by sgl_alloc()
and used to allocate multiple URBs when host controller doesn't
support scatter-gather DMA. The use of uninitialized nents means that
buf_len is zero and use_sg is true. But buffer length should not be
zero when an URB uses scatter-gather DMA.

To prevent this situation, add the conditional that checks buf_len
and use_sg. And move the use of nents right after the sgl_alloc() to
avoid the use of uninitialized nents.

If the error occurs, it adds SDEV_EVENT_ERROR_MALLOC and stub_priv
will be released by stub event handler and connection will be shut
down.

Fixes: ea44d190764b ("usbip: Implement SG support to vhci-hcd and stub driver")

commit 1ec13abac58b6f24e32f0d3081ef4e7456e62ed8 upstream.

USBIP uses lib/scatterlist.h
Hence it needs to set CONFIG_SGL_ALLOC
