Currently the dwc2 doesn't fill in the 'otg_caps' of usb_gadget structure.
When registering a gadget device (e.g. via configfs), the
usb_otg_descriptor_init() checks the 'otg_caps' and 'otg_rev'. It defaults
to HNP and SRP bmAttributes if unspecified. There may be a mismatch with
what's being set in dwc2 params structure. This result in the descriptors
to be miss-configured in this case.
So replace 'otg_cap' bit field by 'otg_caps' structure, so hnp, srp and
otg_rev' can be configured directly in the params.
It's then provided to the gadget struct. These parameters can be tuned
for each platform. In case it's not set, it will default to current
behavior.
Also add option to setup these from the device tree by calling
of_usb_update_otg_caps(). This provides support for standard properties
such as "otg-rev", "hnp-disable" and "srp-disable" (see usb-drd.yaml).

This patch adds the fields UVC_STREAM_PTS and UVC_STREAM_SCR to the uvc
header, in case this data is available. It also enables the copy of the
timestamp to the vb2_v4l2_buffer by setting V4L2_BUF_FLAG_TIMESTAMP_COPY
in the queue.timestamp_flags.

The function uvc_video_encode_header function returns the number of
bytes used for the header. We change the video_encode_isoc_sg function
to use the returned header_len rather than UVCG_REQUEST_HEADER_LEN and
make the encode function more flexible.

The u_audio param fb_max was not set to its default value in f_uac1.c.
As a result the maximum value of Playback Pitch ctl was kept at 1000000,
not allowing to set faster playback pitch for UAC1.
The setting required moving the default constant UAC2_DEF_FB_MAX from
u_uac2.h to FBACK_FAST_MAX in u_audio.h as that header is common for
f_uac1.c and f_uac2.c.

Introduce REPORT_STACK_CANARY to check for differing stack canaries
between two processes (i.e. that an architecture is correctly implementing
per-task stack canaries), using the task_struct canary as the hint to
locate in the stack. Requires that one of the processes being tested
not be pid 1.

Quoted strings should not be split across lines. As put it in [1]:
"never break user-visible strings such as printk messages because that
breaks the ability to grep for them."
While at it, fix the alignment of the arguments in the sentence.
Note: this introduce a checkpatch CHECK: line length of 123 exceeds 100
columns, as the line now is:
vchiq_loud_error("%d: service %d (%c%c%c%c) version mismatch - local (%d, min %d) vs. remote (%d, min %d)",
But now the string is grep-able and the whole function call more
clear.

last_tx_time from struct sreset_priv is no longer used now that
last_tx_complete_time is gone.
This patch removes last_tx_time. This was the last remaining component of
struct sreset_priv, we can now remove the structure itself.
After removing include/rtw_sreset.h, it turned out that some definitions
in .c files were pulled in via rtw_sreset.h. Add the required include
files directly to make compilation succeed without rtw_sreset.h.

The issue happens in an error handling path. If
of_dma_controller_register() fails, the function simply prints error
messages and returns error code, without decrementing the reference
count of pdev->device incremented earlier by
dma_async_device_register(), which may result in refcount leaks.
Fix it by invoking dma_async_device_unregister() before returning the
error code.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.
So, use the purpose specific kcalloc() function instead of the argument
size * count in the kzalloc() function.

Use the helper macro SET_NOIRQ_SYSTEM_SLEEP_PM_OPS() instead of the
verbose operators ".suspend_noirq /.resume_noirq/.freeze_noirq/
.thaw_noirq/.poweroff_noirq/.restore_noirq", because the
SET_NOIRQ_SYSTEM_SLEEP_PM_OPS() is a nice helper macro that could
be brought in to make code a little clearer, a little more concise.

Fault triggers on ioread32() when pci driver unbind is envoked. The
placement of idxd sub-driver removal causes the probing of the device mmio
region after the mmio mapping being torn down. The driver needs the
sub-drivers to be unbound but not release the idxd context until all
shutdown activities has been done. Move the sub-driver unregistering up
before the remove() calls shutdown(). But take a device ref on the
idxd->conf_dev so that the memory does not get freed in ->release(). When
all cleanup activities has been done, release the ref to allow the idxd
memory to be freed.

In rcar_dmac_probe, if pm_runtime_resume_and_get fails, it forgets to

after the success of of_dma_controller_register.

Before the `callback_result` callback was introduced drivers coded their
invocation to the callback in a similar way to:
if (cb->callback) {
spin_unlock(&dma->lock);
cb->callback(cb->callback_param);
spin_lock(&dma->lock);
}
With the introduction of `callback_result` two helpers where introduced to
transparently handle both types of callbacks. And drivers where updated to
look like this:
if (dmaengine_desc_callback_valid(cb)) {
spin_unlock(&dma->lock);
dmaengine_desc_callback_invoke(cb, ...);
spin_lock(&dma->lock);
}
dmaengine_desc_callback_invoke() correctly handles both `callback_result`
and `callback`. But we forgot to update the dmaengine_desc_callback_valid()
function to check for `callback_result`. As a result DMA descriptors that
use the `callback_result` rather than `callback` don't have their callback
invoked by drivers that follow the pattern above.
Fix this by checking for both `callback` and `callback_result` in
dmaengine_desc_callback_valid().

mv_init_host() propagates the value returned by mv_chip_id() which in turn
gets propagated by mv_pci_init_one() and hits local_pci_probe().
During the process of driver probing, the probe function should return < 0
for failure, otherwise, the kernel will treat value > 0 as success.
Since this is a bug rather than a recoverable runtime error we should
use dev_alert() instead of dev_err().
