[PATCH] net/macb: add proper header file

[PATCH] net/macb: add proper header file

[Sudip Mukherjee]

mips allmodconfig build fails with the error:

drivers/net/ethernet/cadence/macb.c: In function 'macb_probe':
drivers/net/ethernet/cadence/macb.c:2908:2: error: implicit declaration of function 'devm_gpiod_get_optional' [-Werror=implicit-function-declaration]

Add the proper header file to resolve it.

A proper fix already has been posted along with the proper device tree
bindinsg too:

Thanks,

Thanks, just compiled with it and the build error for which I posted this patch
is now gone.

This one is fixed and handled by Gregory here:
