Subject: [PATCH 1/2] mmc core block.c: initialize mmc_blk_ioc_data
Commit "mmc: core: Use mrq.sbc in close-ended ffu" adds flags uint to
struct mmc_blk_ioc_data but it does not get initialized for RPMB ioctls
which now fail.
Fix this by always initializing the struct and flags to zero.
Fixes access to RPMB storage.
