Subject: [PATCH 5/5] mmc: block: move multi-ioctl() to use block layer

This switches also the multiple-command ioctl() call to issue all
ioctl()s through the block layer instead of going directly to the devic=

e.

We extend the passed argument with an argument count and loop over all
passed commands in the ioctl() issue function called from the block lay=

er.

quoted

By doing this we are again loosening the grip on the big host lock,
since two calls to mmc_get_card()/mmc_put_card() are removed.

Few more words - we used mmc_utils to run ffu (field firmware update) that =
uses multi-ioctl.
We used Intel NUC with SanDisk storage - this way we could verify that inde=
ed our fw is updated properly.

Cheers,
