From: John Hubbard Date: Mon, 10 Jul 2017 22:49:41 +0000 (-0700) Subject: mm/memory_hotplug.c: remove unused local zone_type from __remove_zone() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a52149f129bd161818fd7a0b6450aaa30a2cbd77;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git mm/memory_hotplug.c: remove unused local zone_type from __remove_zone() __remove_zone() sets up up zone_type, but never uses it for anything. This does not cause a warning, due to the (necessary) use of -Wno-unused-but-set-variable. However, it's noise, so just delete it.
