Subject: [PATCH] driver/core: Fix various warnings due to dev_set_name()
 usage

gcc is too smart, we get:

drivers/base/core.c: In function ‘device_add’:
drivers/base/core.c:877: warning: format not a string literal and no format arguments
drivers/base/core.c: In function ‘__root_device_register’:
drivers/base/core.c:1274: warning: format not a string literal and no format arguments

With 4.3.3 and later. This fixes a bunch of them in drivers/base

There's still more of these elsewhere in the tree and I may send
patches to fix them some day but for now, this takes care of the
driver core.
