Interrupt Storm is observed on the APPS side, when PCIe link down is
simulated, as FW keeps generating interrupts to host, as it's not aware
of the PCIe link down.
When PCIe link down is identified, wlan platform driver schedules work
to start recovery. During Recovery we cut down power to QCA6174, which
stops the interrupt storm. During the window where platform driver
schedule work and the work actually gets schedules, interrupt storm
happened and the APPS triggered watchdog.

Fix issues raised by static analyzer:
1. initialize "retval" before being returned from the driver function.
2. Check return value of the function create_singlethread_workqueue()
and return -ENOMEM if it failed. If creation of the workqueue
failed, then both queue_work() and queue_delayed_work() calls will
later crash, as they expect the workqueue pointer to be a non-NULL
value. Also add clean-up code for this.
3. check return value of the snprintf() call as array 'buf' of size
16 may use index value(s) 16...20.

qseecom_send_modfd_cmd converts ION buffer's virtual address to
scatter gather(SG) list and then sends them to TA by populating
SG list into message buffer. As the physical memory address in
SG list is used directly by TA, this allows a malicious TA to
access/corrupt arbitrary physical memory and may lead to the
process gaining kernel/root privileges. Thus, make changes to
have the QSEEComm driver passing a list of whitelist buffers
that is allowed to be mapped by TA, and the QSEE kernel, in turn,
should add checks to the register_shared_buffer syscall to make
sure the shared buffers an application is mapping falls within
one of these whitelist buffers.

load aggregation. When aggregation is enabled, the total group busy
time is accounted towards the maximum busy CPU of a frequency domain.

accounted and other CPU's group busy time is completely ignored.
Similarly if any CPU other than maximum busy CPU has a pending
notification, its group busy time is accounted twice.

When the notification is pending, don't clip the load to 100% @ fur
