Hardware is a PXA300 with a Marvell 8868 Wifi module attached over SDIO.

Adding Daniel Drake to CC, for 9a821f5d0fc ("libertas: add sd8686 reset_card support").

Looks like mmc_sdio_remove() calls mmc_remove_card() after the reset_card function has called mmc_remove_host() already. Maybe if_sdio_reset_card_worker() should call mmc_free_host() as well?

Thanks,

- Chris.

Adding Daniel Drake to CC, for 9a821f5d0fc ("libertas: add sd8686 reset_card support").
Looks like mmc_sdio_remove() calls mmc_remove_card() after the reset_card function has called mmc_remove_host() already. Maybe if_sdio_reset_card_worker() should call mmc_free_host() as well?
From a quick look is seems we need better housekeeping of the

reset_host variable.

Does this (untested) patch help?

Hardware is a PXA300 with a Marvell 8868 Wifi module attached over SDIO.
Adding Daniel Drake to CC, for 9a821f5d0fc ("libertas: add sd8686 reset_card support").
Looks like mmc_sdio_remove() calls mmc_remove_card() after the reset_card function has called mmc_remove_host() already. Maybe if_sdio_reset_card_worker() should call mmc_free_host() as well?

Or simply mmc_hw_reset()?
