From: Suniel Mahesh <suniel.spartan@xxxxxxxxx>
Mk16_le() is an inline function returning le16_to_cpu()
which is causing type mismatch warnings. Removed Mk16_le() and
replaced it with le16_to_cpu() with appropriate argument type as
suggested by Greg K-H.

Changes for v2:
- Modified commit message, removed Mk16_le() and replaced it with
le16_to_cpu() as suggested by Greg K-H.
- Patches were tested and built on linux-next and staging-testing
