+Subject: [PATCH 48/70] mmc: sdhci-of-esdhc: add/remove some quirks according
+ to vendor version
+
+commit 6c42cb309fee2e126beed6b96a986dc7d85a033d
+[context adjustment]
+
+A previous patch had removed esdhc_of_platform_init() by mistake.
+static void esdhc_of_platform_init(struct sdhci_host *host)
+{
+       u32 vvn;
+
+       vvn = in_be32(host->ioaddr + SDHCI_SLOT_INT_STATUS);
+       vvn = (vvn & SDHCI_VENDOR_VER_MASK) >> SDHCI_VENDOR_VER_SHIFT;
+       if (vvn == VENDOR_V_22)
+               host->quirks2 |= SDHCI_QUIRK2_HOST_NO_CMD23;
+
+       if (vvn > VENDOR_V_22)
+               host->quirks &= ~SDHCI_QUIRK_NO_BUSY_IRQ;
+}
+
+This patch is used to fix it by add/remove some quirks according to
+verdor version in probe.
