It is possible that codec hardware can be reset in case of subsystem
restart scenarios. It is required to reset the codec DSP as well in
such cases to make sure the DSP is in usable state after the codec
hardware is reset. Change adds support to handle codec down and up
events and perform the necessary reset on codec DSP.

The wdsp_intr_handler is not really processing interrupts in interrupt
context, rather assumes that the caller is not in interrupt context and
performs calls that may sleep. Rename the function in order to avoid
confusion. Interrupt handlers can still call this function as long as
they are in threaded interrupt context and are okay to sleep.

One time initializations like regmap and debugfs init are currently
done in the init function. But, in case of subsystem restart, the
driver can get de-initialized and then initialized again. This causes
the debugfs and regmap entries to get removed and added again during
subsystem restart cases. Avoid this by moving all the one time
initialization of the driver to component bind.

In some cases with IPA3 received qmi_service_exit from
modem but still uses invalid qmi-handler to send QMI-msg
to modem which leads to crash. The fix is to add the
check before sending QMI msg to modem.

Add support to read the qcom,lpg-lut-size property from

Yue Cao claims that current host rate limiting of challenge ACKS
(RFC 5961) could leak enough information to allow a patient attacker
to hijack TCP sessions. He will soon provide details in an academic
paper.
This patch increases the default limit from 100 to 1000, and adds
some randomization so that the attacker can no longer hijack
sessions without spending a considerable amount of probes.
Based on initial analysis and patch from Linus.
Note that we also have per socket rate limiting, so it is tempting
to remove the host limit in the future.
v2: randomize the count of challenge acks per second, not the period.

This fixes CVE-2016-0758.
In the ASN.1 decoder, when the length field of an ASN.1 value is extracted,
it isn't validated against the remaining amount of data before being added
to the cursor. With a sufficiently large size indicated, the check:
datalen - dp < 2
may then fail due to integer overflow.
Fix this by checking the length indicated against the amount of remaining
data in both places a definite length is determined.
Whilst we're at it, make the following changes:
(1) Check the maximum size of extended length does not exceed the capacity
of the variable it's being stored in (len) rather than the type that
variable is assumed to be (size_t).
(2) Compare the EOC tag to the symbolic constant ASN1_EOC rather than the
integer 0.
(3) To reduce confusion, move the initialisation of len outside of:
for (len = 0; n > 0; n--) {
since it doesn't have anything to do with the loop counter n.
