There are a large numbers of issues with ASM1051 devices in uas mode:
1) They do not support REPORT SUPPORTED OPERATION CODES
2) They use out of spec 8 byte status iu-s when they have no sense data,
switching to normal 16 byte status iu-s when they do have sense data.
3) They hang / crash when combined with some disks, e.g. a Crucial M500 ssd.
4) They hang / crash when stressed (through e.g. sg_reset --bus) with disks
with which then normally do work (once 1 & 2 are worked around).
Where as in BOT mode they appear to work fine, so the best way forward with
these devices is to just blacklist them for uas usage.
Unfortunately this is easier said then done. as older versions of the ASM1053
(which works fine) use the same usb-id as the ASM1051.
When connected over USB-3 the 2 can be told apart by the number of streams
they support. So this patch adds some less then pretty code to disable uas for
the ASM1051. When connected over USB-2, simply disable uas alltogether for
devices with the shared usb-id.

In the Generic PHY Framework a NULL phy is considered to be a valid phy
thus the "if (hsotg->phy)" check does not give us the information whether
the Generic PHY Framework is used.
In addition to the above this patch also removes phy_init from probe and
phy_exit from remove. This is not necessary when init/exit is done in the
s3c_hsotg_phy_enable/disable functions.

When the driver is removed s3c_hsotg_phy_disable is called three times
instead of once. This results in decreasing of the phy reference counter
below zero and thus consecutive inserts of the module fails.
This patch removes calls to s3c_hsotg_phy_disable from s3c_hsotg_remove
and s3c_hsotg_udc_stop.
s3c_hsotg_udc_stop is called from udc-core.c only after
usb_gadget_disconnect, which in turn calls s3c_hsotg_pullup, which
already calls s3c_hsotg_phy_disable.
s3c_hsotg_remove must be called only after udc_stop, so there is no
point in disabling phy once again there.

Make sure the uwb_dev->bce entry is set before calling uwb_dev_add in
uwbd_dev_onair so that usermode will only see the device after it is
properly initialized. This fixes a kernel panic that can occur if
usermode tries to access the IEs sysfs attribute of a UWB device before
the driver has had a chance to set the beacon cache entry.

Commit 71c731a (usb: host: xhci: Fix Compliance Mode
on SN65LVP3502CP Hardware) implemented a workaround
for a known issue with Texas Instruments' USB 3.0
redriver IC but it left a condition where any xHCI
host would be taken out of reset if port was placed
in compliance mode and there was no device connected
to the port.
That condition would trigger a fake connection to a
non-existent device so that usbcore would trigger a
warm reset of the port, thus taking the link out of
reset.
This has the side-effect of preventing any xHCI host
connected to a Linux machine from starting and running
the USB 3.0 Electrical Compliance Suite because the
port will mysteriously taken out of compliance mode
and, thus, xHCI won't step through the necessary
compliance patterns for link validation.
This patch fixes the issue by just adding a missing
check for XHCI_COMP_MODE_QUIRK inside
xhci_hub_report_usb3_link_state() when PORT_CAS isn't
set.
This patch should be backported to all kernels containing
commit 71c731a.

The PHY configuration is stored in an opaque "config" field, but when
allocating the structure, its proper size needs to be known. In the case
of UTMI, the proper structure is tegra_utmip_config of which a local
variable already exists, so we can use that to obtain the size from.
Fixes the following warning from the sparse checker:

Up to now, when endpoint addresses in descriptors were non-consecutive,
there were created redundant files, which could cause problems in kernel,
when user tried to read/write to them. It was result of fact that maximum
endpoint address was taken as total number of endpoints in function.
This patch adds endpoint descriptors counting and storing their addresses
in eps_addrmap to verify their cohesion in each speed.
Endpoint address map would be also useful for further features, just like
vitual endpoint address mapping.

This patch fixes the condition of is_done in usbhsf_dma_push_done().
This function will be called after a transmission finished by DMAC.
So, the function should check if the transmission packet is short packet
or not. Also the function should call try_run to send the zero packet
by the pio handler if the "*is_done" is not set. Otherwize, the
transaction will not finish if a gadget driver sets the "zero" flag
in a transmission.

This patch protects the mod->irq_bempsts and mod->irq_brdysts by
spin lock in the usbhs_status_get_each_irq() because other functions
will write them during spin lock. Otherwise, the driver will clears
the BRDYSTS and/or BEMPSTS wrongly, and then, the transaction will not
finish.
Also since the driver should use the INTSTS0 and BRDYSTS and BEMPSTS
as the same timing, the patch protects them.

Sierra Wireless Direct IP devices using the 68A3 product ID
can be configured for modes including a CDC ECM class function.
The known example uses interface numbers 12 and 13 for the ECM
control and data interfaces respectively, consistent with CDC
MBIM function interface numbering on other Sierra devices.
It seems cleaner to restrict this driver to the ff/ff/ff
vendor specific interfaces rather than increasing the already
long interface number blacklist. This should be more future
proof if Sierra adds more class functions using interface
numbers not yet in the blacklist.

spi: Bug fixes for v3.17
A smattering of bug fixes for the SPI subsystem, all in driver code
which has seen active work recently and none of them with any great
global impact.
There's also a new ACPI ID for the pxa2xx driver which required no code
changes and the addition of kerneldoc for some structure fields that
were missing it and generating warnings during documentation builds as a
result.

- Fix for an ACPI regression related to the handling of fixed events
that caused netlink routines to be (incorrectly) run in interrupt
context from Lan Tianyu
