[PATCH 0/2] cma: do some clean up

[Xishi Qiu]

1. use "PFN_DOWN(r->size)" instead of "r->size >> PAGE_SHIFT".
2. adjust the function structure, one for the success path, 
the other for the failure path.

Xishi Qiu (2):
  cma: use macro PFN_DOWN when converting size to pages
  cma: adjust goto branch in function cma_create_area()
