   8 [context adjustment]

  10 A previous patch had removed esdhc_of_platform_init() by mistake.
  11 static void esdhc_of_platform_init(struct sdhci_host *host)
  12 {
  13         u32 vvn;
  14
  15         vvn = in_be32(host->ioaddr + SDHCI_SLOT_INT_STATUS);
  16         vvn = (vvn & SDHCI_VENDOR_VER_MASK) >> SDHCI_VENDOR_VER_SHIFT;
  17         if (vvn == VENDOR_V_22)
  18                 host->quirks2 |= SDHCI_QUIRK2_HOST_NO_CMD23;
  19
  20         if (vvn > VENDOR_V_22)
  21                 host->quirks &= ~SDHCI_QUIRK_NO_BUSY_IRQ;
  22 }
  23
  24 This patch is used to fix it by add/remove some quirks according to
  25 verdor version in probe.
