[OpenWrt-Devel] [PATCH] procd: remove /dev filter on uevents

I had a brief discussion with John on this matter and was being told
that the reason for this filter was to optimize boot time.

When we remove the /dev filter, boot time will increase considerably on
lower end devices due to the resulting hotplug-call overhead of the huge
volume of additional uevents.

A better approach here would be to selectively whitelist uevents based
on subsystem or similar attributes, e.g. `DEVTYPE=usb_device`.
