[PATCH 1/2] of: always define of_node_cmp() and other functions

From: Arnd Bergmann
Date: Wed Feb 03 2016 - 17:01:04 EST


The ti-vpe driver started using of_node_cmp(), and it can
be used when CONFIG_OF is disabled, which results in a
build failure:

drivers/media/platform/ti-vpe/cal.c: In function 'of_get_next_port':
drivers/media/platform/ti-vpe/cal.c:1655:12: error: implicit declaration of function 'of_node_cmp' [-Werror=implicit-function-declaration]

There is no reason for this, we can simply move the definition
outside of the #ifdef CONFIG_OF section without any downsides.
