commit faeb0731be0a31e2246b21a85fa7dabbd750101d upstream.
In xilinx_dma_child_probe function, the nr_channels variable is passed to of_property_read_u32() which expects an u32 return value pointer. Modify the nr_channels variable type from int to u32 to fix the incompatible parameter coverity warning.
Addresses-Coverity: Event incompatible_param.
