       "This is the second attempt after the first one failed miserably and
        got zapped to unblock the rest of the interrupt related patches.
      
        A treewide cleanup of interrupt descriptor (ab)use with all sorts of
        racy accesses, inefficient and disfunctional code. The goal is to
        remove the export of irq_to_desc() to prevent these things from
        creeping up again"

      Swap the calling sequence of krealloc() and __request_region(), call the
      latter first. In this way, the value of dev_dax->nr_range does not need to
      be considered when __request_region() failed.
