Subject: [PATCH -next] <linux/of.h>: add stub for of_get_next_parent() to fix
 qcom build error

From: Randy Dunlap <rdunlap@...radead.org>

Fix a (COMPILE_TEST) build error when CONFIG_OF is not set/enabled
by adding a stub for of_get_next_parent().

../drivers/soc/qcom/qcom-geni-se.c:819:11: error: implicit declaration of function 'of_get_next_parent'; did you mean 'of_get_parent'? [-Werror=implicit-function-declaration]
../drivers/soc/qcom/qcom-geni-se.c:819:9: warning: assignment makes pointer from integer without a cast [-Wint-conversion]
