Qmuxd bridge daemon is opening /dev/gps before USB enumerated with
USB composition having GPS interface as part of it. This daemon
performs EP_LOOKUP ioctl and encounters failure. It keeps retrying
for some iterations, and later goes into sleep and doesn't perform
any IOs. This results into no GPS related IOs between daemon and
host side QMUXD driver. Hence this change sends zero length packet
for MBIM (as QBI also faces same issue) and GPS interface when
USB cable is connected and those interfaces are part of USB
composition. Both QBI and Qmuxd bridge daemon are now wait for zero
length packet as indication for change in USB cable status, and
queries using GSI_MBIM_GPS_USB_STATUS IOCTL (newly added). Based on
this IOCTL related response, both daemons performs read/write with
created control devices.

A number of kthread-related functions indirectly take task_struct->pi_lock
while holding worker->lock in the call chain like this:
spin_lock(&worker->lock)
kthread_insert_work
wake_up_process
try_to_wake_up
raw_spin_lock_irqsave(&p->pi_lock, flags)
This lock dependency exists whenever kthread_insert_work is called either
directly or indirectly via __kthread_queue_delayed_work in the following
functions:
kthread_queue_work
kthread_delayed_work_timer_fn
kthread_queue_delayed_work
kthread_flush_work
kthread_mod_delayed_work
This creates possibilities for circular dependencies like the one reported
at [1]. Break this lock dependency by moving task wakeup after worker->lock
has been released.

If emergency system shutdown is called, like by thermal shutdown,
dm device could be alive when the block device couldn't process
I/O requests anymore. In this status, the handling of I/O errors
by new dm I/O requests or by those already in-flight can lead to
a verity corruption state, which is misjudgment.
So, skip verity work for I/O error when system is shutting down.

Pull the RFR line before doing stop_rx in uart driver.
This is to prevent any rx data to come into the uart rx fifo when
stop_rx is being executed.
Remove the rx length zero check in
handling dma rx to prevent race conditions with EOT and DMA_DONE
interrupt bits.
Issue scenarios could be that during baud rate change/ runtime
suspend or any other place where stop_rx is used, there might
be a race between rx data entering uart rx fifo and availability
of dma buffers in uart driver. In this scenarios there will
be interrupt storm with rx water mark interrupt.

Currently, interrupts of qcom-spmi-adc5 driver are registered
with name "pm-adc5". However on platforms with multiple PMICs
that can have different ADC types (adc5 or adc7), this naming
is not user friendly when looking at interrupt data. Add a name
that looks unique for different adc types so that they can be
interpreted easily.
