    mmc: block: fix the host's claim-release in special request · ef3a69c7
    Seungwon Jeon authored
    For normal request mmc_blk_issue_rq is called twice with asynchronous
    transfer(cur and prev). Host's claim and release can be done in each
    mmc_blk_issue_rq. However, Special request is currently excluded in
    asynchronous transfer. After special request is finished, if there is
    no new request, mmc_release_host won't be called in mmc_blk_issue_rq.
    The problem is founded during mmc_suspend.
