There is a checkpatch warning:
WARNING: struct dev_pm_ops should normally be const
#279: FILE: drivers/mmc/host/sdhci-pltfm.h:102:
+extern struct dev_pm_ops sdhci_pltfm_pmops;
total: 0 errors, 1 warnings, 0 checks, 310 lines checked
> V3: remove unused local var in sdhci-pci.c
> V2: sdhci-s3c does not use sdhci-pltfm.c and gets its own dev_pm_ops.
