You may as well leave it in place here, after you call get_datactrl_cfg(). > + datactrl = host->ops->get_datactrl_cfg(host); Otherwise, I don't see a problem with this, although it would be nice to avoid the overhead of so many public functions, which could be done by adding them as inline functions in mmci.h -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 12.1Mbps down 622kbps up According to speedtest.net: 11.9Mbps down 500kbps up
