when running mmc_rescan_try_freq(), try to init two times with last frequency.
For example, assume that host->f_min is 400KHz, we can find the below message.
mmc1: mmc_rescan_try_freq: trying to init card at 400000 Hz
mmc1: mmc_rescan_try_freq: trying to init card at 400000 Hz
i didn't find to mention about this..why try to init the two times with same frequency?
Is there any reason? If i missed the history, plz let me know them.
I think that trial is not necessary. Trial needs to running with other frequency.
