So Suspend-to-RAM and Suspend-to-idle are failing on Exynos5250 Snow. Add the keep-power-in-suspend Power Management property to the SDIO/MMC node so the mwifiex suspend handler doesn't fail and the system is able to enter into a suspend state. Signed-off-by: Javier Martinez Canillas --- Kukjin and Krzysztof, I didn't notice that Snow was also missing this property when I did the same change for Peach Pit and and Pi Chromebooks [0], sorry about that.
