From: Russell King Date: Fri, 25 Apr 2014 11:59:26 +0000 (+0100) Subject: mmc: sdhci: convert sdhci_set_uhs_signaling() into a library function X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=96d7b78cfc2fd6b1539704e2d33239dbaa097cc4;p=linux-beck.git mmc: sdhci: convert sdhci_set_uhs_signaling() into a library function Add sdhci_set_uhs_signaling() and always call the set_uhs_signaling method. This avoids quirks being added into sdhci_set_uhs_signaling().
