Also, while looking around found the similar warning for other file where it uses " of_device_get_match_data()" drivers/pci/controller/pcie-iproc-platform.c:56:15: warning: cast to smaller integer type 'enum iproc_pcie_type' from 'const void *' [-Wvoid-pointer-to-enum-cast] pcie->type = (enum iproc_pcie_type) of_device_get_match_data(dev); Thanks -Amit
