diag: dci: Preventing unitialized stack memcpy operation

At certain point in diag driver there can be memcpy operation
for the unintialized stack. Due to uninitilization of memory
user can obatin valuable information on accessing this stack
in userspace. This patch fixes that issue.

usb: misc: mdm_ctrl_bridge: Honor device polling interval

Driver is not using polling interval from device end point
descriptor. Instead driver is using hard coded value which
is inconsistent with the polling frequency required by the
endpoint of the device. If device requires polling interval
shorter than hard coded value it leads to latency to the
end to end communication. Hence use polling interval from
endpoint descriptor of attached device.

slim_ngd: Handle runtime-pm resume error gracefully

Runtime-pm resume for satellite driver may fail if ADSP is going
through subsystem-restart. Handle that error, and set runtime-pm's
status to suspended if resume fails. Resume typically fails due to
failure to wake slimbus from pause_clock. Make sure another wakeup
can be tried later when ADSP comes back up

slimbus: Manage channel slots only if framework manages bandwidth

If slimbus controller overrides bandwidth management, channel slots

Slimbus controller will go into idle mode due to this change when
channel setup/teardown is done. Make sure controller can transition
states correctly in runtime-pm suspend, and system-suspend case.

msm: qmi: Match service version and instance during lookup

The remote subsystems construct instance_id from the version and service-
registered instance information. The version field is used to identify the
compatibility between client and service. The instance field is used to
uniquely identify a service from multiple instances of the same service_id
and version.

Currently the kernel QMI client interface matches only the instance during
the service lookup. Update the kernel QMI client interface to construct
instance_id from the version and instance information during lookup.

systems with synchronous CPUs.
