Subject: [PATCH] [net-next] net: ipconfig: move ic_nameservers_fallback into #ifdef block

From: Arnd Bergmann <[email-masked]>
Date: Fri, 19 May 2023 11:32:38 +0200

From: Arnd Bergmann <[email-masked]>

The new variable is only used when IPCONFIG_BOOTP is defined and otherwise
causes a warning:

net/ipv4/ipconfig.c:177:12: error: 'ic_nameservers_fallback' defined but not used [-Werror=unused-variable]

Move it next to the user.

Fixes: 81ac2722fa19 ("net: ipconfig: Allow DNS to be overwritten by DHCPACK")
