Grain-media GM12U320 based devices are mini video projectors using USB for
both power and video data transport.
Their usb-storage interface is a virtual windows driver CD.
The gm12u320 kms driver needs these interfaces to talk to the device and
export it as framebuffer & kms dri device nodes, so make sure that the
usb-storage driver does not bind to it.

This device automatically switches itself to another mode (0x1405)
unless the specific access pattern of Windows is followed in its
initial mode. That makes a dirty unmount of the internal storage
devices inevitable if they are mounted. So the card reader of
such a device should be ignored, lest an unclean removal become
inevitable.
This replaces an earlier patch that ignored all LUNs of this device.
That patch was overly broad.

This patch fixes a bug introduced by commit 977dcfdc60 ("USB: OHCI:
don't lose track of EDs when a controller dies"). The commit changed
ed_state from ED_UNLINK to ED_IDLE too early, before finish_urb() had
been called. The user-visible consequence is that the driver
occasionally crashes or locks up when an URB is submitted while
another URB for the same endpoint is being unlinked.
This patch moves the ED state change later, to the right place. The
drawback is that now we may unnecessarily execute some instructions
multiple times when a controller dies. Since controllers dying is an
exceptional occurrence, a little wasted time won't matter.

Commit 25cd2882e2 ("usb/xhci: Change how we indicate a host supports
Link PM.") removed the code to set lpm_capable for USB 3.0 super-speed
root hub. The intention of that change was to avoid touching usb core
internal field, a.k.a. lpm_capable, and let usb core to set it by
checking U1 and U2 exit latency values in the descriptor.
Usb core checks and sets lpm_capable in hub_port_init(). Unfortunately,
root hub is a special usb device as it has no parent. Hub_port_init()
will never be called for a root hub device. That means lpm_capable will
by no means be set for the root hub. As the result, lpm isn't functional
at all in Linux kernel.
This patch add the code to check and set lpm_capable when registering a
root hub device. It could be back-ported to kernels as old as v3.15,
that contains the Commit 25cd2882e2 ("usb/xhci: Change how we indicate
a host supports Link PM.").

the transition from Resume state to U0.
With the fix of xhci: report U3 when link is in resume state, it also
exposes an issue that usb3 roothub and controller can suspend right
after phase 1, and this causes a hard hang in controller.
To fix the issue, we need to prevent usb3 bus suspend if any port is

When resetting a device the number of active TTs may need to be
corrected by xhci_update_tt_active_eps, but the number of old active
endpoints supplied to it was always zero, so the number of TTs and the
bandwidth reserved for them was not updated, and could rise
unnecessarily.
This affected systems using Intel's Patherpoint chipset, which rely on
software bandwidth checking. For example, a Lenovo X230 would lose the
ability to use ports on the docking station after enough suspend/resume
cycles because the bandwidth calculated would rise with every cycle when
a suitable device is attached.
The correct number of active endpoints is calculated in the same way as
in xhci_reserve_bandwidth.

virt_dev->num_cached_rings counts on freed ring and is not updated
correctly. In xhci_free_or_cache_endpoint_ring() function, the free ring
is added into cache and then num_rings_cache is incremented as below:
virt_dev->ring_cache[rings_cached] =
virt_dev->eps[ep_index].ring;
virt_dev->num_rings_cached++;
here, free ring pointer is added to a current index and then
index is incremented.
So current index always points to empty location in the ring cache.
For getting available free ring, current index should be decremented
first and then corresponding ring buffer value should be taken from ring
cache.
But In function xhci_endpoint_init(), the num_rings_cached index is
accessed before decrement.
virt_dev->eps[ep_index].new_ring =
virt_dev->ring_cache[virt_dev->num_rings_cached];
virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL;
virt_dev->num_rings_cached--;
This is bug in manipulating the index of ring cache.
And it should be as below:
virt_dev->num_rings_cached--;
virt_dev->eps[ep_index].new_ring =
virt_dev->ring_cache[virt_dev->num_rings_cached];
virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL;

bnx2x: update FW, rebrand and more
This patch series does several things - it updates the bnx2x FW into
7.12.30 which both contains some small fixes as well as opening the door
for several new features for the device - mainly vxlan/geneve offloads
and vlan filtering offload.
It then adds a new Multi-function mode [BD] which requires this FW in
order to operate.
In addition, this finally rebrands the driver from a 'broadcom' driver
into a 'qlogic' driver [although it would still reside under Broadcom's

This moves bnx2x into using 7.12.30 FW. Said firmware fixes the following:
- Packets from a VF with pvid configured which were sent with a
different vlan were transmitted instead of being discarded.
- FCoE traffic might not recover after a failue while there's traffic
to another function.
In addition, this FW opens the door for the driver to implement several
new features; Specifically, this enhances the device's support for
encapsulated packets and will allow vxlan/geneve offloads to be added in
the future, as well as vlan filtering offload.

usb: fixes for v4.2-rc4
Only four fixes this time so I'll describe them all.
We have an iomen resource leak fix in mv_udc_core. This bug
exists since v3.3.
Renesas got a fix for how they use dma_map_single() with IOMMU.
The new ulpi bus got an ordering fix, so drivers don't try to
probe ahead of the bus.
And finally, we have a fix for a really old regression with
dwc3, one which could only be exposed by a recent patch from
Subbaraya. Basically, we were startving the controller of
transfer resources.
