ASoC: wcd9304:Fix RX voice in handset call distort after reboot the device

Issue:The RX voice in handset call will distorted from handset after
      reboot the device
Root cause:This happens due enable override gain in cp_static register.

Fix:Configure the cp_static override gain as Half gain.

msm: audio: qdsp6v2: Change acdb_mmap size variable to unsigned

The acdb_mmap fuction does a size calculation but
stores the result in an int which makes negitive
numbers possible. Changing the variable to unsigned
ensures that the size used is never out of bounds.

ASoC: msm: qdsp6v2: Fix buffer overflow in voice driver

Userspace registers calibration data with acdb driver
through ioctls. Voice driver registers the calibration
data with CVD by querying acdb data from acdb driver and
copies the calibration data in apr message.

The size of the calibration data can be controlled by userspace
and can result in buffer overflow if the calibration size is
greater than the destination buffer size.
Reject acdb data if the size is greater than the size of
destination buffer.

This change initializes kernel space stack variables
that are passed between kernel space and user space
using ioctls.
Non initialization of these variables may lead to

ARM: 7809/1: perf: fix event validation for software group leaders

It is possible to construct an event group with a software event as a
group leader and then subsequently add a hardware event to the group.
This results in the event group being validated by adding all members
of the group to a fake PMU and attempting to allocate each event on
their respective PMU.

Unfortunately, for software events wthout a corresponding arm_pmu, this
results in a kernel crash attempting to dereference the ->get_event_idx
function pointer.

This patch fixes the problem by checking explicitly for software events
and ignoring those in event validation (since they can always be
scheduled). We will probably want to revisit this for 3.12, since the
validation checks don't appear to work correctly when dealing with
multiple hardware PMUs anyway.

This is because event->attr.config in armpmu_event_init()

is never checked against the size of the array indexed in
armpmu_map_hw_event(). Fix the problem by checking the value of
config before indexing the array and rejecting invalid config
values.
