Subject: Input: evbug - identify device by its sysfs ID
X-Git-Tag: firefly_0821_release~17958^2~53
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=819561286b8eca845ce741141a016de2b51e90c7;p=firefly-linux-kernel-4.4.55.git

Input: evbug - identify device by its sysfs ID

This should help with devices that don't set up their phys or name
since sysfs ID is always present.
