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/clocksource/timer-ti-dm.c:40:
drivers/clocksource/timer-ti-dm.c:973:26: error: expected ',' or ';' before 'DRIVER_NAME'
MODULE_ALIAS("platform:" 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/clocksource/timer-ti-dm.c:973:1: note: in expansion of macro 'MODULE_ALIAS'
MODULE_ALIAS("platform:" DRIVER_NAME);
^~~~~~~~~~~~
Caused by commit
6a26793a7891 ("moduleparam: Save information about built-in modules in separate file")
DRIVER_NAME is not defined and this kbuild tree change has exposed it.
It has been this way since commit
df28472a1b28 ("ARM: OMAP: dmtimer: platform driver")
From v3.2-rc1 in 2011.
I have applied the following patch for today.

Subject: [PATCH] arm: omap: remove unused MODULE_ALIAS from timer-ti-dm.c
DRIVER_NAME has never been defined, so this cannot have ever been used.
