      md: fix incorrect declaration about claim_rdev in md_import_device · b0907cad
      Adrian Huang authored
      Commit fb541ca4 ("md: remove lock_bdev / unlock_bdev") removes
      wrappers for blkdev_get/blkdev_put. However, the uninitialized local
      static variable of pointer type 'claim_rdev' in md_import_device()
      is NULL, which leads to the following warning call trace:
      
        WARNING: CPU: 22 PID: 1037 at block/bdev.c:577 bd_prepare_to_claim+0x131/0x150

      It turns out the md device cannot be used:
      
        md: could not open device unknown-block(259,0).
        md: md127 stopped.
      
      Fix the issue by declaring the local static variable of struct type
      and passing the pointer of the variable to blkdev_get_by_dev().
