[PATCH 0/2] Fix memory leaks in virtio & remoteproc cores
Hi,
The following patches fix couple of memory leaks in the virtio and
remoteproc cores when using these as modules, and going through a
cycle of insmod and rmmod with at least a device registered with
the corresponding cores in between. I ran into this on our downstream
product kernels on both 3.14 and 4.1 based kernels, and should apply
to the latest kernel as well.
Patches can be picked up

[PATCH 0/2] hwrng: don't fetch data before device init
Hi,
When booting a recent kernel under KVM with the virtio-rng device
enabled, the boot process was stalling. Bisect pointed to a commit
made during the 3.15 window to fetch randomness from newly-registered
devices in the hwrng core. The details are in the patches.
I considered a couple of approaches, but basing on the init() function
being registered, as is done in patch 1 here, seems like
