I confirm this patch fixes below compilation failure on sandbox
(LIBAVB=y, AVB_VERIFY=y, FASTBOOT=y, BLK=y):

common/avb_verify.c: In function ‘mmc_read_and_flush’:
common/avb_verify.c:291:18: error: ‘struct mmc’ has no member named ‘block_dev’
  blks = part->mmc->block_dev.block_read(part->mmc_blk,
                  ^~
common/avb_verify.c: In function ‘mmc_write’:
common/avb_verify.c:330:18: error: ‘struct mmc’ has no member named ‘block_dev’
  return part->mmc->block_dev.block_write(part->mmc_blk,

With this patch, avb_verify compiles equally well with BLK=y and BLK=n.
