The part I can't figure out is that git blame tells me there's already an
export:

3b9334ac835bb (Pawel Moll      2014-04-30 16:46:29 +0100 154)   return regmap;
3b9334ac835bb (Pawel Moll      2014-04-30 16:46:29 +0100 155) }
b33cdd283bd91 (Arnd Bergmann   2014-05-26 17:25:22 +0200 156) EXPORT_SYMBOL_GPL(devm_regmap_init_vexpress_config);
3b9334ac835bb (Pawel Moll      2014-04-30 16:46:29 +0100 157)

but I can't figure out where or if drivers/power/reset/vexpress-poweroff.c gets
a MODULE_LICENSE from...
