Been there. This mainly works for platform independent drivers. In this case:

  CC      drivers/net/ethernet/renesas/sh_eth.o
drivers/net/ethernet/renesas/sh_eth.c: In function 'sh_eth_dev_init':
drivers/net/ethernet/renesas/sh_eth.c:1274:2: error: implicit declaration of function 'sh_eth_reset' [-Werror=implicit-function-declaration]
drivers/net/ethernet/renesas/sh_eth.c: In function 'sh_eth_drv_probe':
drivers/net/ethernet/renesas/sh_eth.c:2724:13: error: 'sh_eth_my_cpu_data' undeclared (first use in this function)
drivers/net/ethernet/renesas/sh_eth.c:2724:13: note: each undeclared identifier is reported only once for each function it appears in
drivers/net/ethernet/renesas/sh_eth.c: At top level:
drivers/net/ethernet/renesas/sh_eth.c:889:12: warning: 'sh_eth_check_reset' defined but not used [-Wunused-function]
