[james_p_freyensee at linux.intel.com]

PTI driver bug fixes concerning spec, memory leak, and a code review.
    
This patch contains 3 random bug fixes:
1. PTI HW spec says 128 channels, not 256
2. memory leak bug
3. code eliminated that was flagged from an open-source code
   review on a different driver.

This requires the "PTI Alan Cox bug fix/equality patch" that was sent for PTI patch application before this one.
