From 638bdc8ce845285e1112f4870aded1638187fc98 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 3 Nov 2015 15:00:57 +0100 Subject: [PATCH] dmaengine: edma: fix build without CONFIG_OF During the edma rework, a build error was introduced for the case that CONFIG_OF is disabled: drivers/built-in.o: In function `edma_tc_set_pm_state': :(.text+0x43bf0): undefined reference to `of_find_device_by_node' As the edma_tc_set_pm_state() function does nothing in case we are running without OF, this adds an IS_ENABLED() check that turns the function into an empty stub then and avoids the link error.
