4.5-stable review patch. If anyone has any objections, please let me know.
------------------ From: Lucas Stach <[email protected]> commit 3491b69045b1926a198ba70dc1296ca253f2fbdd upstream. The new code to do the clock rate setting externally to the SDMMC module has a shortcut to not propagate changes with a 0 rate to the CAR by simply bailing out. This breaks proper cutting of the card clock. Fix it by directly calling the correct sdhci function.
