This version of the patch doesn't apply cleanly or compile -- maybe you
have a later revision?

/home/cjb/git/mmc/drivers/mmc/host/sdhci-dove.c: In function ‘sdhci_dove_probe’:
/home/cjb/git/mmc/drivers/mmc/host/sdhci-dove.c:109:2: error: implicit declaration of function ‘clk_unprepare_disable’ [-Werror=implicit-function-declaration]
/home/cjb/git/mmc/drivers/mmc/host/sdhci-dove.c:111:1: warning: label ‘sdhci_dove_allocate_fail’ defined but not used [-Wunused-label]

Thanks,

- Chris.
