of: fix declaration of of_io_request_and_map
We are having build failure with linux-next for sparc allmodconfig with the error messages: drivers/built-in.o: In function `meson6_timer_init': meson6_timer.c:(.init.text+0x5fe8): undefined reference to `of_io_request_and_map' drivers/built-in.o: In function `mtk_timer_init': mtk_timer.c:(.init.text+0x6af0): undefined reference to `of_io_request_and_map' drivers/built-in.o: In function `asm9260_timer_init': asm9260_timer.c:(.init.text+0x6c48): undefined reference to `of_io_request_and_map' CONFIG_OF is defined for sparc so it is expected that we have a definition of of_io_request_and_map() but of/address.c is only compiled if it is !SPARC. In other words, CONFIG_OF_ADDRESS is not defined for sparc so we get the build failure. Fixes: e572f844ca66 ("clocksource/drivers/meson6: Add the COMPILE_TEST option") Fixes: bec8c4617611 ("clocksource/drivers/mediatek: Add the COMPILE_TEST option") Fixes: 4a373b45f94a ("clocksource/drivers/asm9260: Add the COMPILE_TEST option") Acked-by: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Sudip Mukherjee <sudip@vectorindia.org> [robh: move include of io.h out of ifdef's] Signed-off-by: Rob Herring <robh@kernel.org>
