Subject: tegra: mmc: Set the removable flag correctly
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=707ac1ad17c09a952b366709d98a5f454cfab909;p=project%2Fbcm63xx%2Fu-boot.git

tegra: mmc: Set the removable flag correctly

If the mmc device is non-removable (as indicated by the device tree), set
the flag so that users of the device know.
