[PATCH] powerpc: Fix unused function warning 'lmb_to_memblock'
From: <hidden>
Date: 2016-08-01 06:34:00
From: Alastair D'Silva <redacted>
This patch fixes the following warning:
arch/powerpc/platforms/pseries/hotplug-memory.c:323:29: error: 'lmb_to_memblock' defined but not used [-Werror=unused-function]
static struct memory_block *lmb_to_memblock(struct of_drconf_cell *lmb)
^~~~~~~~~~~~~~~
The only consumer of this function is 'dlpar_remove_lmb', which is
enabled with CONFIG_MEMORY_HOTREMOVE, so move it into the same
ifdef block.
