Hi Anson,

looks like there may be some dependency which haven't landed in the
networking tree yet? Because this doesn't build:

drivers/net/ethernet/freescale/fec_main.c: In function âfec_probeâ:
drivers/net/ethernet/freescale/fec_main.c:3561:9: error: implicit declaration of function âplatform_get_irq_byname_optionalâ; did you mean âplatform_get_irq_optionalâ? [-Werror=implicit-function-declaration]
3561 | irq = platform_get_irq_byname_optional(pdev, irq_name);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| platform_get_irq_optional
cc1: some warnings being treated as errors

Could you please repost once that's resolved? Please add Andy's and
Stephen's acks when reposting.

Thank you!
