Miaohe Lin 0edf61e5ee khugepaged: remove unneeded return value of khugepaged_collapse_pte_mapped_thps() 
Patch series "Cleanup and fixup for khugepaged", v2.

This series contains cleanups to remove unneeded return value, use
helper function and so on.  And there is one fix to correct the wrong
result value for trace_mm_collapse_huge_page_isolate().

This patch (of 4):

The return value of khugepaged_collapse_pte_mapped_thps() is never checked
since it's introduced.  We should remove such unneeded return value.
