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

From: Arnd Bergmann
Date: Fri May 19 2023 - 05:35:49 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

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")
