[PATCH v3] platform: Make platform_bus device a platform device
Pawel Moll
pawel.moll at arm.com
Tue Jul 22 10:55:19 PDT 2014
... describing the root of the device tree, so one can write
a platform driver initializing the platform.
There has been a lot of references to platform_bus device where
it didn't make any sense, because simply using NULL as a parent
will make the device be adopted by the top level anyway.

Changes since v2:
* replaced references to platform_bus.dev with NULL
in places where it shouldn't make any difference
Changes since v1:
* rebased on top of v3.16-rc6
* fixed up all new explicit references to platform_bus,
with majority in mach-shmobile; 99% of them seem completely
useless and I was *very* tempted to replace them with
NULL - all reasons for and against this are welcomed
