We currently check for hwx->idx < 0 in armpmu_read and armpmu_del
unnecessarily. The only case where hwc->idx < 0 is when armpmu_add
fails, in which case the event's state is set to
PERF_EVENT_STATE_INACTIVE.
The perf core will not attempt to read from an event in
PERF_EVENT_STATE_INACTIVE, and so the check in armpmu_read is
unnecessary. Similarly, if perf core cannot add an event it will not
attempt to delete it, so the WARN_ON in armpmu_del is unnecessary.
This patch removes these two redundant checks.

Currently perf_pmu_register may fail for several reasons (e.g. being
unable to allocate memory for the struct device it associates with each
PMU), and while any error is propagated by armpmu_register, it is
ignored by cpu_pmu_device_probe and not propagated to the caller. This
also results in a leak of a struct arm_pmu.
This patch adds cleanup if armpmu_register fails, and updates the info
messages to better differentiate this type of failure from a failure to
probe the PMU type from the hardware or dt.

Two hooks in hda_gen_spec, cap_sync_hook and capture_switch_hook, play
very similar roles. The only differences are that the former is
called more often (e.g. at init or switching capsrc) while the latter
can take an on/off argument.
As a more generic implementation, consolidate these two hooks, and
pass snd_ctl_elem_value pointer as the second argument. If the
secondary argument is non-NULL, it can take the on/off value, so the
caller handles it like the former capture_switch_hook. If it's NULL,
it's called in the init or capsrc switch case.

Add a check against possible Rx timestamp freezing in the hardware via
watchdog mechanism. This situation can occur when an Rx timestamp has been
latched, but the packet has been dropped because the Rx ring is full.
Whenever a packet comes in that should be timestamped, the Rx timestamp
gets latched into the hardware registers and we will store the jiffy value
in the rx_ring. The watchdog will keep track of his own jiffy timer
whenever there is no valid timestamp in the registers.
If the watchdog detects a valid timestamp in the registers, meaning that no
Rx packet has consumed it yet, it will check which time is most recent: the
last time in the watchdog or any time in the rx_rings. If the most recent
"event" was more than 5 seconds ago, it will flush the Rx timestamp and
print a warning message to the syslog.

start_slot: used to retrieve all request of SG during cleanup
dwc3_gadget_giveback: We need to skip link TRB if it was one of the
intermediate TRB of SG.
dwc3_prepare_one_trb: We need to track all submitted TRBs during
cleanup. Since, all TRBs would be serially allocated, so we can just
keep starting slot info and we can always find rest of them. We need to
pass sg node number, so that we cab appropriately program ISOC_FIRST/ISOC,
Chain etc.
dwc3_prepare_trbs: last_one should be set when it is last node
of SG as well as last node of request_list.
__dwc3_cleanup_done_trbs: It has been prepared after re-factorization of
dwc3_cleanup_done_reqs. It is called for each TRB of SG.

There were still some corner cases where isoc transfer was not able to
restart, specially when missed isoc does not happen , and in fact gadget does
not queue any new request during giveback.
Cleanup function calls giveback first, which provides a way to queue
another request to gadget. But gadget did not had any data. So , it did
not call ep_queue. To twist it further, gadget did not queue till
cleanup for last queued TRB is called. If we ever reach this scenario,
we must call END TRANSFER, so that we receive a new xfernotready with
information about current microframe number.
Also insure that there is no request submitted to core when issuing END
TRANSFER.

There are two reasons to generate missed isoc.
1. when the host does not poll for all the data.
2. because of application-side delays that prevent all the data from
being transferred in programmed microframe.
Current code was able to handle first case only. This patch handles
scenario 2 as well.Scenario 2 sometime may occur with complex gadget
application, however it can be easily reproduced for testing purpose as
follows:
a. use isoc binterval as 1 in f_sourcesink.
b. use pattern=0
c. introduce a delay of 150us deliberately in source_sink_complete, so
that after few frames it lands into scenario 2.
d. now run testusb 16 (isoc in test). You will notice that if this
patch is not applied then isoc transfer is not able to recover after
first missed.
Current patch's approach is as under:
If missed isoc occurs and there is no request queued then issue END
TRANSFER, so that core generates next xfernotready and we will issue a
fresh START TRANSFER.
If there are still queued request then wait, do not issue either END or
UPDATE TRANSFER, just attach next request in request_list during giveback.
If any future queued request is successfully transferred then we will issue
UPDATE TRANSFER for all request in the request_list.

The function dma_controller_create() references

This is often because dma_controller_create lacks a __init

This warning is there due to the deficiency in the commit 07a67bbb (usb: musb:

Since the start() method is only called from musb_init_controller() which is
