Staging: sst: add ioctls for post processing algorithm interface
This patch adds two new ioctls to intel_sst_ctrl device.
This i/f can be used by application to send algorithm parameters
Signed-off-by: Vinod Koul <vinod.koul@intel.com>
[This will need further discussion in the context of the final ALSA interface
but is fine for staging, ie anyone who relies on it should expect changes
Also fixed a missing kmalloc fail check]
