During unrelated work, attempting to remove an include of the linux/module.h in favour of "struct module;" in order to reduce header entanglement, we found doing so caused a build failure in this file. mach-pxa/spitz.c: In function 'spitz_bl_kick_battery': mach-pxa/spitz.c:524:2: error: implicit declaration of function 'symbol_get' [-Werror=implicit-function-declaration] mach-pxa/spitz.c:524:12: warning: assignment makes pointer from integer without a cast [enabled by default] mach-pxa/spitz.c:527:3: error: implicit declaration of function 'symbol_put' [-Werror=implicit-function-declaration] It turns out this file uses symbol_get/symbol_put which live in the module.h header, but it wasn't including module.h -- which was being masked by the module.h in include/linux/gpio/driver.h - the one we want to remove/replace. With ARM and GPIO being different subsystems, we'll need to get this in ARM 1st, and then wait a release before changing the GPIO header, otherwise we'll risk triggering build failures.
