msm_serial_hs: Set the driver data in the probe correctly

* Set the UART driver data correctly so we can access it later to
  control the clocks externally.

Change-Id: Ie0691c5a11cb4e98c2c3cb5cc2d052b7776ebcab
msm: audio: qdsp6v3: Add size safety check to ACDB driver

Check that the size sent by userspace is not larger
then the internal amount allowed. This protects
against overflowing the stack due to an invalid size.
sched: fix OOPS when build_sched_domains percpu allocation fails

Under extreme memory used up situation, percpu allocation
might fails. We hit it when system go to suspend-to-ram.
