It looks like we intended to return an error code here, because we

When us->extra is null the driver is not initialized, however, a
later call to osd200_scsi_to_ata is made that dereferences
us->extra, causing a null pointer dereference. The code
currently detects and reports that the driver is not initialized;
add a return to avoid the subsequent dereference issue in this
check.
Thanks to Alan Stern for pointing out that srb->result needs setting
to DID_ERROR << 16

This commit adds the vboxvideo drm/kms driver for the virtual graphics
card used in Virtual Box virtual machines to drivers/staging.
Why drivers/staging? This driver is already being patched into the kernel
by several distros, thus it is good to get this driver upstream soon, so
that work on the driver can be easily shared.
At the same time we want to take our time to get this driver properly
cleaned up (mainly converted to the new atomic modesetting APIs) before
submitting it as a normal driver under drivers/gpu/drm, putting this
driver in staging for now allows both.
Note this driver has already been significantly cleaned up, when I started
working on this the files under /usr/src/vboxguest/vboxvideo as installed
by Virtual Box 5.1.18 Guest Additions had a total linecount of 52681
lines. The version in this commit has 4874 lines.

The register for the "new timing mode" also has bit fields for setting
output and sample timing phases. According to comments in Allwinner's
BSP kernel, the default values are good enough.
Keep the default values already in the hardware when setting new timing

Once the Windows guest is shutdown, the display pipe will be disabled
and intel_gvt_check_vblank_emulation will be called to check if the
vblank timer is turned off. Given the scenario of creating VM1 ,VM2,
destoying VM2 in current code, VM1 has pipe enabled and continues to
check VM2, the flag have_enabled_pipe is always false since all the VM2
pipes are disabled, so the vblank timer will be canceled and TDR happens
in Windows VM1 guest due to the vsync timeout.
In this patch the vblank timer will be never canceled once one pipe is
enabled.
v2:
- remove have_enabled_pipe flag and check pipe enabled directly. (Zhenyu)

When new directory 'DIR1' is created in a directory 'DIR0' with SGID bit
set, DIR1 is expected to have SGID bit set (and owning group equal to
the owning group of 'DIR0'). However when 'DIR0' also has some default
ACLs that 'DIR1' inherits, setting these ACLs will result in SGID bit on
'DIR1' to get cleared if user is not member of the owning group.
Fix the problem by creating __ext2_set_acl() function that does not call
posix_acl_update_mode() and use it when inheriting ACLs. That prevents
SGID bit clearing and the mode has been properly set by
posix_acl_create() anyway.

A recent optimization was made so that a request put on the
pending_list wouldn't get mapped for DMA until just before
preparing a TRB for it. However, this poses a problem in case
the request is dequeued or the endpoint is disabled before the
mapping is done as that would lead to dwc3_gadget_giveback()
unconditionally calling usb_gadget_unmap_request_for_dev() with
an invalid request->dma handle. Depending on the platform's DMA
implementation the unmap operation could result in a panic.
Since we know a successful mapping is a prerequisite for getting
a TRB, the unmap can be conditionally called only when req->trb
is non-NULL.

IRQ_NOAUTOEN cannot be used with shared IRQs, since commit 04c848d39879
("genirq: Warn when IRQ_NOAUTOEN is used with shared interrupts") and
kernel now throws a warn dump. But OMAP DWC3 driver uses this flag. As
per commit 12a7f17fac5b ("usb: dwc3: omap: fix race of pm runtime with
irq handler in probe") that introduced this flag, PM runtime can race
with IRQ handler when deferred probing happens due to extcon,
therefore IRQ_NOAUTOEN needs to be set so that irq is not enabled until
extcon is registered.
Remove setting of IRQ_NOAUTOEN and move the registration of
shared irq to a point after dwc3_omap_extcon_register() and
of_platform_populate(). This avoids possibility of probe deferring and
above said race condition.

The Gru device tree currently contains entries for the regulators
ppvar_bigcpu, ppvar_litcpu, ppvar_gpu and ppvar_centerlogic; however,
the regulators have not been enabled, due to the lack of binding and driver
support for keeping the over-voltage protection (OVP) at bay and
preventing unintended regulator shutdowns on voltage downshifts.
Now, the vctrl regulator driver has been merged, along with new bindings
for asymmetric settling time. The driver is OVP aware, it splits larger
voltage decreases in multiple steps when necessary and adds required
delays.
This change renames each of the aforementioned regulators to
<orig_name>_pwm and adds a new vctrl regulator named <orig_name>.
The vctrl regulators use the voltage of their corresponding PWM regulator
as control voltage. The OVP related values are empirical and stem from
the Chrome OS kernel tree.

As reported by Éric Piel on the Comedi mailing list (see
<https://groups.google.com/forum/#!topic/comedi_list/ueZiR7vTLOU/discussion>),
the analog output asynchronous commands are running too fast with a
period 50 ns shorter than it should be. This affects all boards with AO
command support that are supported by the "ni_pcimio", "ni_atmio", and
"ni_mio_cs" drivers.
This is a regression bug introduced by commit 080e6795cba3 ("staging:
comedi: ni_mio_common: Cleans up/clarifies ni_ao_cmd"), specifically,
this line in `ni_ao_cmd_set_update()`:
/* following line: N-1 per STC */
ni_stc_writel(dev, trigvar - 1, NISTC_AO_UI_LOADA_REG);
The `trigvar` variable value comes from a call to `ni_ns_to_timer()`
which converts a timer period in nanoseconds to a hardware divisor
value. The function already reduces the divisor by 1 as required by the
hardware, so the above line should not reduce it further by 1. Fix it
by replacing `trigvar` by `trigvar - 1` in the above line, and remove
the misleading comment.

====================
bcmgenet: Fragmented SKB corrections
Two issues were observed in a review of the bcmgenet driver support for
fragmented SKBs which are addressed by this patch set.
The first addresses a problem that could occur if the driver is not able
to DMA map a fragment of the SKB. This would be a highly unusual event
but it would leave the hardware descriptors in an invalid state which
should be prevented.
The second is a hazard that could occur if the driver is able to reclaim
the first control block of a fragmented SKB before all of its fragments
have completed processing by the hardware. In this case the SKB could
be freed leading to reuse of memory that is still in use by hardware.

Since the skb is attached to the first control block of a fragmented
skb it is possible that the skb could be freed when reclaiming that
control block before all fragments of the skb have been consumed by
the hardware and unmapped.
This commit introduces first_cb and last_cb pointers to the skb
control block used by the driver to keep track of which transmit
control blocks within a transmit ring are the first and last ones
associated with the skb.
It then splits the bcmgenet_free_cb() function into transmit
(bcmgenet_free_tx_cb) and receive (bcmgenet_free_rx_cb) versions
that can handle the unmapping of dma mapped memory and cleaning up
the corresponding control block structure so that the skb is only
freed after the last associated transmit control block is reclaimed.

In case we fail to map a single fragment, we would be leaving the
transmit ring populated with stale entries.
This commit introduces the helper function bcmgenet_put_txcb()
which takes care of rewinding the per-ring write pointer back to
where we left.
It also consolidates the functionality of bcmgenet_xmit_single()
and bcmgenet_xmit_frag() into the bcmgenet_xmit() function to
make the unmapping of control blocks cleaner.

Commit 07d4510f5251 ("dt-bindings: net: bgmac: add bindings documentation for
bgmac") added both brcm,amac-nsp.txt and brcm,bgmac-nsp.txt. The former is
actually the one that got updated and is in use by the bgmac driver while the
latter is duplicating the former and is not used nor updated.
Fixes: 07d4510f5251 ("dt-bindings: net: bgmac: add bindings documentation for bgmac")

====================
Constify isdn pci_device_id's.
pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.
