net: ll_temac: Use of_property_read_u32 instead of open-coding it
Use of_property_read_u32 to read the "clock-frequency" property instead of using of_get_property with return value checks. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Reviewed-by: Sören Brinkmann <soren.brinkmann@xilinx.com> Signed-off-by: David S. Miller <davem@davemloft.net>
