The helper function mx27_setup_weimcs() references IOMEM() and IMX_IO_P2V() but without required header mach/hardware.h included in mx27.h. This will break the build of those mx27 file with no direct inclusion of mach/hardware.h, or when indirect inclusion to mach/hardware.h breaks. For example, when the inclusion of mach/hardware.h gets removed from mach/gpio.h, we will see the following compile error. CC arch/arm/mach-imx/pm-imx27.o In file included from arch/arm/mach-imx/pm-imx27.c:14:0: arch/arm/plat-mxc/include/mach/mx27.h: In function ‘mx27_setup_weimcs’: arch/arm/plat-mxc/include/mach/mx27.h:138:2: error: implicit declaration of function ‘IOMEM’ arch/arm/plat-mxc/include/mach/mx27.h:138:2: error: implicit declaration of function ‘IMX_IO_P2V’ This patch removes mx27_setup_weimcs() from mx27.h and makes it local to mach-pcm038.c, which is the only user for this helper.
