The new tag 'emm' seems not suitable here, keep the original 'eclk' here, 
modify the upper 'eclk' tags instead:
...
        ret = i2c_pxa_probe_dt(dev, i2c, &i2c_type);
        if (ret > 0)
                ret = i2c_pxa_probe_pdata(dev, i2c, &i2c_type);
        if (ret < 0)
-               goto eclk;
+               goto etype;

        res = platform_get_resource(dev, IORESOURCE_MEM, 0);
        irq = platform_get_irq(dev, 0);
        if (res == NULL || irq < 0) {
                ret = -ENODEV;
-               goto eclk;
+               goto edev;
        }

        if (!request_mem_region(res->start, resource_size(res), res->name)) {
                ret = -ENOMEM;
-               goto eclk;
+               goto emem;
        }
...

   eclk:
        release_mem_region(res->start, resource_size(res));
   etype:
   edev:
   emem:
        kfree(i2c);
