Subject: [PATCH -next 1/8] dax/bus.c: Make dax_region_rwsem and dax_dev_rwsem static

The sparse tool complains as follows:

drivers/dax/bus.c:19:1: warning:
	symbol 'dax_region_rwsem' was not declared. Should it be static?

drivers/dax/bus.c:25:1: warning:
	symbol 'dax_dev_rwsem' was not declared. Should it be static?

These symbols are not used outside bus.c, so marks them static.
