      sdhci: only reprogram retuning timer when flag is set · 2bc02485
      Arend van Spriel authored
      When the host->tuning_count is zero it means that the retuning is
      disabled. This is checked on the first run of sdhci_execute_tuning()
      by the if statement below:
      
      	if (!(host->flags & SDHCI_NEEDS_RETUNING) && host->tuning_count &&
      	    (host->tuning_mode == SDHCI_TUNING_MODE_1)) {
      
      So only when tuning_count is non-zero it will set the host flag
      SDHCI_USING_RETUNING_TIMER. The else statement is only for re-programming
      the timer, which means that flag must be set. Because that is not checked
      the else statement is executed in the first run when tuning_count is zero.
      
      This was seen on a host controller which indicated SDHCI_TUNING_MODE_1 (0)
      and tuning_count being zero. Suspect that (one of) these registers is not
      properly set.
