This patch adds a inline dummy implementations of_find_matching_node() in "#ifdef CONFIG_OF" else part. Without this patch,build system can lead to issues. This was discovered during randconfig testing,in which ARM_CCI was enabled w/o CONFIG_OF being enabled,leading to the following error: CC drivers/bus/arm-cci.o drivers/bus/arm-cci.c: In function ‘cci_probe’: drivers/bus/arm-cci.c:971:2: error: implicit declaration of function ‘of_find_matching_node’ [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors make[2]: *** [drivers/bus/arm-cci.o] Error 1 make[1]: *** [drivers/bus] Error 2 make: *** [drivers] Error 2 Signed-off-by: Manjunath Goudar <manju.goudar@xxxxxxx> Cc: Grant Likely <grant.likely@xxxxxxxxxx> Cc: Rob Herring <rob.herring@xxxxxxxxxxx> Cc: devicetree@xxxxxxxxxxxxxxx Cc: linux-kernel@xxxxxxxxxxxxxxx --- include/linux/of.h | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/include/linux/of.h b/include/linux/of.h index f95aee3..2c57aa2 100644 --- a/include/linux/of.h +++ b/include/linux/of.h @@ -340,6 +340,13 @@ int of_device_is_stdout_path(struct device_node *dn); #else /* CONFIG_OF */ +static inline struct device_node *of_find_matching_node( + struct device_node *from, + const struct of_device_id *matches) +{ + return NULL; +} + static inline const char* of_node_full_name(struct device_node *np) { return "<no-node>"; -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
