[PATCH] drivers/net/wan/z85230.c: Use designated initializers

From: Kees Cook
Date: Sun Jul 30 2017 - 21:31:38 EST


In preparation for the randstruct gcc plugin performing randomization of
structures that are entirely function pointers, use designated initializers
so the compiler doesn't get angry.

This is a prerequisite for the future randstruct fptr randomization. I'd
prefer to carry this in my gcc-plugin tree for v4.14 with an Ack from
someone on net-dev, or if possible, have it applied to v4.13 via net-dev.

Thanks!
