Apparently, the fixed-link's gpio's FLAG_REQUESTED bit remained set
causing gpiod_request_commit to return -EBUSY in (v4.18.0):
[<c0667750>] (gpiod_request_commit) from [<c066890c>] (gpiod_request+0x64/0x88)
[<c066890c>] (gpiod_request) from [<c066a338>] (gpiod_get_from_of_node+0x48/0x13c)

[<c0949d2c>] (phy_device_register) from [<c094e824>] (fixed_phy_register+0xe8/0x1f8)

[<c0964908>] (macb_probe) from [<c086ebec>] (platform_drv_probe+0x48/0x98)
But that's a separate issue, I'll remove this line from the commit message...
