From: Russell King Date: Fri, 25 Apr 2014 11:58:45 +0000 (+0100) Subject: mmc: sdhci: move setting host->clock into sdhci_do_set_ios() X-Git-Tag: firefly_0821_release~176^2~3794^2~37 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=373073efd06528867df963724a93f29c7d5534d0;p=firefly-linux-kernel-4.4.55.git mmc: sdhci: move setting host->clock into sdhci_do_set_ios() We don't need implementations to do this, since the only time it's necessary is when we change the clock, and the only place that happens is in sdhci_do_set_ios(). So, move it there, and remove it from the iMX platform backend.
