[PATCH V5 02/13] mmc: core: Add members to mmc_request and mmc_data for CQE's

Adrian Hunter
2017-08-10T12:14:53Z

Most of the information needed to issue requests to a CQE is already in
struct mmc_request and struct mmc_data. Add data block address, some flags,
and the task id (tag), and allow for cmd being NULL which it is for CQE
tasks.
