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.
