char: hw_random: drop owner assignment from platform_drivers
...
A platform_driver does not need to set an owner, it will be populated by the
driver core.

hwrng: bcm2835 - fix oops when rng h/w is accessed during registration
...
Commit "d9e7972 hwrng: add randomness to system from rng sources"
exposed a bug in the bcm2835-rng driver resulting in boot failure
on Raspberry Pi due to the following oops:
[ 28.261523] BUG: soft lockup - CPU#0 stuck for 23s! [swapper:1]
[ 28.271058]
[ 28.275958] CPU: 0 PID: 1 Comm: swapper Not tainted 3.14.0+ #11
[ 28.285374] task: db480000 ti: db484000 task.ti: db484000
[ 28.294279] PC is at bcm2835_rng_read+0x28/0x48
[ 28.302276] LR is at hwrng_register+0x1a8/0x238
.
.
.
The RNG h/w is not completely initialized and enabled before
hwrng_register() is called and so the bcm2835_rng_read() fails.
Fix this by making the warmup/enable writes before registering
the RNG source with the hwrng core.

drivers/char: delete non-required instances of include <linux/init.h>
...
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

hwrng: bcm2835: fix MODULE_LICENSE tag
...
The MODULE_LICENSE macro invocation must use either "GPL" or "GPL v2",
but not "GPLv2" in order to be detected by the module loader.
This fixes the allmodconfig build error:
FATAL: modpost: GPL-incompatible module bcm2835-rng.ko uses GPL-only symbol 'platform_driver_unregister'
