mmc: core: properly init drv_type

2017-12-05T16:14:00+00:00

mmc: mmc: Enable Command Queuing

2017-10-30T10:45:50+00:00

mmc: core: Introduce host claiming by context

2017-10-30T10:45:49+00:00

Currently the host can be claimed by a task. Change this so that the host can be claimed by a context that may or may not be a task. This provides for the host to be claimed by a block driver queue to support blk-mq, while maintaining compatibility with the existing use of mmc_claim_host().
