Subject: [IA64] fix arch/ia64/mm/contig.c:235: warning: unused variable `nid'
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8b9c106856d92c8266697328b148d115538b59ce;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[IA64] fix arch/ia64/mm/contig.c:235: warning: unused variable `nid'

This warning only shows up with CONFIG_VIRTUAL_MEM_MAP=y and
CONFIG_FLATMEM=y.

There is only one caller left for register_active_ranges() from the
contig.c code ... so it doesn't need to pick up the node number, the
node number is always zero.
