msm: vidc: Validate input data before processing
Bluetooth: Adding HCI Dev lock for set_active and set_sniff routines.

When data transfer is in progress on a ACL connection, all the time
the set_active_mode API will be called to update the timer for next
sniff mode. If there is ACL disconnect triggered from remote side,
there is possibility of hci connection delete when set_active
routine in progress. Found a condition where delete API destroyed
the wake lock, which is used in set_active API. In codition leads
to crash in set_wakelock API. The current change is to lock hdev,
before set_active and set_sniff APIs are called. This avoids the
race condition in accessing hci connection, while delete in progress
and vice versa.

Bluetooth: Check for both SCO and ESCO types in hci_connect API.

In hci_connect API there is check for existing link, before
connect operation in order to avoid queuing connect if connection
already exist. This check for Synchronous connections is not
validating for ESCO and SCO connection types which are possible
synchronous connections.The current change takes care of verifying
both before proceeding to add a new connection.

Bluetooth: Validate hci conn validity before refering wakelock.

Found in a rare case there is possibility that remote device
sent disconnect on a connection and DUT is trying send data
on the same. In that case accessing some released wakelock
is causing issue. The current changes are to use locking
mechanism to validate the connection before acting on the
wake lock.

bluetooth: LE conn whitelist implementation

Add support to create connection to LE devices using
whitelist. With this, the Controller can try to connect
to multiple devices at the same time. The following
interfaces are added.
1. Add/Remove device from whitelist
2. Clear all the devices from whitelist
3. Create Connection to devices from whitelist
4. Cancel create connection to whitelist devices

kgsl_pwrscale: Rework policy sysfs implementation

In the current implementation, the pwrscale policy kobj is
created when the pwrscale driver initializes.  It is then added
to the kobj hierarchy when a governor adds sysfs files.

When a governor removes sysfs files, it frees the kobj.

Then, when a new governor starts up, it attempts to add an
uninitialized kobj.  This fails.

Instead, use a constant kobj for the policy directory,
and add governor-specific attributes under it.  If a
sysfs group is given a name, all attributes in the group
will appear in a subdirectory with that name (see cpufreq
governor tuning variables).  Use this approach for our
governor tuning.

TODO (possibly in a future patch) - Rework this so the
governor attributes can be groups attached directly to
the pwrscale kobj.

kgsl: Implement conservative scaling policy

This behaves similarly to the conservative cpufreq governor,
which is similar to how most Mali GPU scaling algorithms behave.

The "trustzone" policy that is default relies on an undocumented
black box to make scaling decisions.

How to enable:
echo conservative > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/pwrscale/policy

Conservative attr group:
/sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/pwrscale/policy_config/conservative

Polling interval (10-1000):
/sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/pwrscale/policy_config/conservative/polling_interval

Enable stats printing (causes microlags on low polling intervals):
echo 1 > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/pwrscale/policy_config/conservative/print_stats

NOTE:
- perms are set to 666 for testing purposes
