mmc: mmci: Add qcom dml support to the driver.

Hello Srinivas Kandagatla,

The patch 4dd5a1e6dd12: "mmc: mmci: Add qcom dml support to the driver." from Jul 29, 2014, leads to the following static checker warning:

	drivers/mmc/host/mmci_qcom_dml.c:131 dml_hw_init()
	warn: unsigned 'producer_id' is never less than zero.

drivers/mmc/host/mmci_qcom_dml.c

   121  /* Initialize the dml hardware connected to SD Card controller */
   122  int dml_hw_init(struct mmci_host *host, struct device_node *np)
   123  {
   124          u32 config;
   125          void __iomem *base;
   126          u32 consumer_id, producer_id;
   127  
   128          consumer_id = of_get_dml_pipe_index(np, "tx");
   129          producer_id = of_get_dml_pipe_index(np, "rx");
   130  
   131          if (producer_id < 0 || consumer_id < 0)
                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

132 return -ENODEV;

Hi Dan,

Thankyou for reporting this warning.

Both consumer_id and producer_id are supposed to be int instead of u32. I will fix this.

Thanks,
