dmaengine/ARM: omap-dma: Fix the DMAengine compile test on non OMAP configs (a8db115e) · Commits · 戴 / test

The DMAengine driver for omap-dma use three function calls from the plat-omap legacy driver. When the DMAengine driver is built when ARCH_OMAP is not set, the compilation will fail due to missing symbols. Add empty inline functions to allow the DMAengine driver to be compiled with COMPILE_TEST. Signed-off-by:
