usb: xhci: handle both SSIC ports in PME stuck quirk

2016-02-17T20:31:01+00:00

commit fa89537783cb442263fa5a14df6c7693eaf32f11 upstream.

Commit abce329c27b3 ("xhci: Workaround to get D3 working in Intel xHCI")
adds a workaround for a limitation of PME storm caused by SSIC port in
some Intel SoCs. This commit only handled one SSIC port, while there
are actually two SSIC ports in the chips. This patch handles both SSIC
ports. Without this fix, users still see PME storm.

usb: phy: msm: fix error handling in probe.

2016-02-17T20:31:01+00:00

commit a38a08dfaaab978dced63aa9cad45f0f62e23a66 upstream.

This driver registers for extcon events as part of its probe, but
never unregisters them in case of error in the probe path.

There were multiple issues noticed due to this missing error handling.
One of them is random crashes if the regulators are not ready yet by the
time probe is invoked.

Ivan's previous attempt [1] to fix this issue, did not really address
all the failure cases like regualtor/get_irq failures.

usb: cdc-acm: send zero packet for intel 7260 modem

2016-02-17T20:31:01+00:00

commit ffdb1e369a73b380fce95b05f8498d92c43842b4 upstream.

For Intel 7260 modem, it is needed for host side to send zero
packet if the BULK OUT size is equal to USB endpoint max packet
length. Otherwise, modem side may still wait for more data and
cannot give response to host side.

usb: cdc-acm: handle unlinked urb in acm read callback

2016-02-17T20:31:01+00:00

commit 19454462acb1bdef80542061bdc9b410e4ed1ff6 upstream.

In current acm driver, the bulk-in callback function ignores the
URBs unlinked in usb core.

This causes unexpected data loss in some cases. For example,
runtime suspend entry will unlinked all urbs and set urb->status
to -ENOENT even those urbs might have data not processed yet.
Hence, data loss occurs.

This patch lets bulk-in callback function handle unlinked urbs
to avoid data loss.

USB: option: fix Cinterion AHxx enumeration

2016-02-17T20:31:01+00:00

commit 4152b387da81617c80cb2946b2d56e3958906b3e upstream.

In certain kernel configurations where the cdc_ether and option drivers
are compiled as modules there can occur a race condition in enumeration.
This causes the option driver to enumerate the ethernet(wwan) interface
as usb-serial interfaces.

usb: hub: do not clear BOS field during reset device

2016-02-17T20:31:01+00:00

commit d8f00cd685f5c8e0def8593e520a7fef12c22407 upstream.

In function usb_reset_and_verify_device, the old BOS descriptor may
still be used before allocating a new one. (usb_unlocked_disable_lpm
function uses it under the situation that it fails to disable lpm.)
So we cannot set the udev->bos to NULL before that, just keep what it
was. It will be overwrite when allocating a new one.
