Module Name: src
Committed By: jakllsch
Date: Thu Dec 20 14:37:00 UTC 2012
Modified Files:
src/sys/dev/cardbus: sdhc_cardbus.c
src/sys/dev/sdmmc: sdhc.c sdhcvar.h
Log Message:
Change sdhc_detach so that it detaches all host controllers at once.
This should make multiple slot controllers, for example those with
a controller on more than one PCI/CardBus BAR, detach with fewer bugs.
Tested with as-of-yet-uncommited sdhc_pci changes on a single-host
ExpressCard JMicron JMB38[89].
