I had to add a:

diff --git a/drivers/mmc/host/sdhci-pci.c b/drivers/mmc/host/sdhci-pci.c
index 22581a1..48061b3 100644
--- a/drivers/mmc/host/sdhci-pci.c

 #include <linux/dma-mapping.h>
 #include <linux/slab.h>
 #include <linux/device.h>
+#include <linux/pm_runtime.h>
 
 #include <linux/mmc/host.h>
 
to prevent a compile error.
