Hi Masahiro, After merging the kbuild tree, today's linux-next build (arm multi_v7_defconfig) failed like this: In file included from include/linux/module.h:18, from drivers/mfd/omap-usb-tll.c:21: drivers/mfd/omap-usb-tll.c:462:26: error: expected ',' or ';' before 'USBHS_DRIVER_NAME' MODULE_ALIAS("platform:" USBHS_DRIVER_NAME); ^~~~~~~~~~~~~~~~~ include/linux/moduleparam.h:26:47: note: in definition of macro '__MODULE_INFO' = __MODULE_INFO_PREFIX __stringify(tag) "=" info ^~~~ include/linux/module.h:164:30: note: in expansion of macro 'MODULE_INFO' #define MODULE_ALIAS(_alias) MODULE_INFO(alias, _alias) ^~~~~~~~~~~ drivers/mfd/omap-usb-tll.c:462:1: note: in expansion of macro 'MODULE_ALIAS' MODULE_ALIAS("platform:" USBHS_DRIVER_NAME); ^~~~~~~~~~~~ Caused by commit 6a26793a7891 ("moduleparam: Save information about built-in modules in separate file") USBHS_DRIVER_NAME is not defined and this kbuild tree change has exposed it. It has been this way since commit 16fa3dc75c22 ("mfd: omap-usb-tll: HOST TLL platform driver") From v3.7-rc1 in 2012. I have applied the following patch for today. From: Stephen Rothwell Date: Mon, 6 May 2019 09:39:14 +1000 Subject: [PATCH] mfd: omap: remove unused MODULE_ALIAS from omap-usb-tll.c USBHS_DRIVER_NAME has never been defined, so this cannot have ever been used.
