There is a unnecessary return statement at the end of
void function cma_activate_area.
This can be dropped.
While at it, also fix another warning related to unsigned.
These are reported by checkpatch as well.
WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
+unsigned cma_area_count;
WARNING: void function return statements are not generally useful
