This patch adds a of_find_node_by_phandle() and of_get_next_parent()
function declaration dependence on"#ifdef CONFIG_OF" in "include/linux/of.h"
else part return inline dummy implementations (returning NULL). Without
this patch,build system can lead to issues. This was discovered during
randconfig testing,in which VEXPRESS_CONFIG was enabled w/o CONFIG_OF
being enabled,leading to the following error:
CC drivers/mfd/vexpress-config.o
drivers/mfd/vexpress-config.c: In function ‘__vexpress_config_func_get’:
