[ Upstream commit 1160d61bc51e87e509cfaf9da50a0060f67b6de4 ]
The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to request_irq() (which takes
*unsigned* IRQ #s), causing it to fail with -EINVAL (overridden by -ENODEV
further below). Stop calling request_irq() with the invalid IRQ #s.

with the loop upper limit of num_parents that is an int type.
There is a potential infinite loop if num_parents is larger than

[ Upstream commit 77db0ec8b7764cb9b09b78066ebfd47b2c0c1909 ]
When running in Azure, disks may be connected to a Linux VM with
read/write caching enabled. If a VM panics and issues a VMbus
UNLOAD request to Hyper-V, the response is delayed until all dirty
data in the disk cache is flushed. In extreme cases, this flushing
can take 10's of seconds, depending on the disk speed and the amount
of dirty data. If kdump is configured for the VM, the current 10 second
timeout in vmbus_wait_for_unload() may be exceeded, and the UNLOAD
complete message may arrive well after the kdump kernel is already
running, causing problems. Note that no problem occurs if kdump is
not enabled because Hyper-V waits for the cache flush before doing
a reboot through the BIOS/UEFI code.
Fix this problem by increasing the timeout in vmbus_wait_for_unload()
to 100 seconds. Also output periodic messages so that if anyone is
watching the serial console, they won't think the VM is completely
hung.

When KEXEC is disabled, the UV build fails:
arch/x86/platform/uv/uv_nmi.c:875:14: error: ‘uv_nmi_kexec_failed’ undeclared (first use in this function)
Since uv_nmi_kexec_failed is only defined in the KEXEC_CORE #ifdef branch,
this code cannot ever have been build tested:
if (main)
pr_err("UV: NMI kdump: KEXEC not supported in this kernel\n");
atomic_set(&uv_nmi_kexec_failed, 1);
Nor is this use possible in uv_handle_nmi():
atomic_set(&uv_nmi_kexec_failed, 0);
These bugs were introduced in this commit:
d0a9964e9873: ("x86/platform/uv: Implement simple dump failover if kdump fails")
Which added the uv_nmi_kexec_failed assignments to !KEXEC code, while making the
definition KEXEC-only - apparently without testing the !KEXEC case.
Instead of complicating the #ifdef maze, simplify the code by requiring X86_UV
to depend on KEXEC_CORE. This pattern is present in other architectures as well.
( We'll remove the untested, 7 years old !KEXEC complications from the file in a
separate commit. )

Currently it leaves unhandled interrupts unmasked, but those are never
acked. In the case of a "device idle" interrupt, this leads to an
effectively frozen system until plugging it in.

When the EP0 IN request was not completed but less than a packet sent,
it would complete the request successfully. That doesn't make sense
and can't really happen as fotg210_start_dma always sends
min(length, maxpkt) bytes.

For a 75 Byte request, it would send the first 64 separately, then detect
that the remaining 11 Byte fit into a single DMA, but due to this bug set
the length to the original 75 Bytes. This leads to a DMA failure (which is
ignored...) and the request completes without the remaining bytes having
been sent.

before calling adf_iov_putmsg()->mutex_lock(vf2pf_lock), however the
vf2pf_lock is initialized in adf_dev_init(), which can fail and when it
fail, the vf2pf_lock is either not initialized or destroyed, a subsequent
