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:

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.

From: Stephen Rothwell <s...@canb.auug.org.au>
Date: Mon, 6 May 2019 09:26:24 +1000
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.
