The patchset fixes a deadlock situation of runtime PM methods and minimize
card detection "deadtime" during runtime suspending.

in suspend
method and defer the autosuspend if the slot is loaded. The default 2
second autosuspend delay of USB subsystem should let the next polling
detects the card.

Invent MMC_POWER_UNDEFINED to describe the initial host power_mode which
might be either off or turned on by an early driver such as BIOS or UEFI driver.
This lets the later mmc_power_off() do actual power-off things and power_mode
will be in a known state eventually.
Roger Tseng (2):
mmc: core
oking
mmc_power_off() in mmc_start_host() is more than NOP now and triggers
real power-off and re-init in sdhci.
Will this be OK?
