    mmc: block: remove the check of packed for packed request routine · 96e52daa
    Shawn Lin authored
    packed should always exist without calling its cleanup function
    explicitly. Moreover, we have use it when preparing packed list.
    So I don't believe we should ever fall into this check again when
    doing mmc_blk_packed_hdr_wrq_prep or mmc_blk_end_packed_req,etc.
    And the code of mmc_blk_end_packed_req is trying to use packed before
    checking it which makes it quite weird. This patch is trying to
    remove these two checks and move it to the mmc_blk_prep_packed_list.
    If we find packed is null, then we should never use MMC_BLK_PACKED_CMD.
    By doing this, we could fall back to non-packed request if finding null
    packed, though it's impossible theoretically.
    
    After removing these two BUG_ONs, we also remove all other similar
    checks within the routine of mmc_blk_issue_rw_rq which checks the
    error handling of packed request.
