Summary
mmc: core: Fix kernel panic when remove non-standard SDIO card
Details

In the Linux kernel, the following vulnerability has been resolved:

mmc: core: Fix kernel panic when remove non-standard SDIO card

SDIO tuple is only allocated for standard SDIO card, especially it causes memory corruption issues when the non-standard SDIO card has removed, which is because the card device's reference counter does not increase for it at sdioinitfunc(), but all SDIO card device reference counter gets decreased at sdioreleasefunc().
