Previously, <linux/module.h> was included before ralink_regs.h in all ralink files - leading to <linux/io.h> being implicitly included. After commit 26dd3e4ff9ac ("MIPS: Audit and remove any unnecessary uses of module.h") removed the inclusion of module.h from multiple places, some ralink platforms failed to build with the following error: In file included from arch/mips/ralink/mt7620.c:17:0: ./arch/mips/include/asm/mach-ralink/ralink_regs.h: In function ‘rt_sysc_w32’: ./arch/mips/include/asm/mach-ralink/ralink_regs.h:38:2: error: implicit declaration of function ‘__raw_writel’ [-Werror=implicit-function-declaration] __raw_writel(val, rt_sysc_membase + reg); ^ ./arch/mips/include/asm/mach-ralink/ralink_regs.h: In function ‘rt_sysc_r32’: ./arch/mips/include/asm/mach-ralink/ralink_regs.h:43:2: error: implicit declaration of function ‘__raw_readl’ [-Werror=implicit-function-declaration] return __raw_readl(rt_sysc_membase + reg); Fix this by including <linux/io.h>.
