From 6eadae1a14afdb5352d900a2577084c13ae273a3 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Mon, 29 Feb 2016 21:56:24 +0100 Subject: mmc: tegra: properly disable card clock 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.
