From fcd71d9cc6e301bdbd71829b79e80168473ca609 Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Tue, 8 Dec 2015 14:17:55 +0530 Subject: [PATCH] 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.
