This patch enables sdhci-acpi devices to suspend/resume asynchronously. This will improve system suspend/resume speed. After enabling the sdhci-acpi devices and all their child devices to suspend/resume asynchronously on ASUS T100TA, the system suspend-to-idle time is reduced from 1645ms to 1089ms, and the system resume time is reduced from 940ms to 908ms.
