4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Harvey Hunt <harvey.hunt@imgtec.com>
commit e3ccf1d1dee5129beb839fe05c61eb134131bdd6 upstream.
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>.
