From 6ce4cc278deca9849bd54783294be7edbe24bac0 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 21 Jan 2016 18:13:41 -0800 Subject: [PATCH] greybus: add bundle class to the bundle uevent When bundles are added and then removed, we have a race where we go to read the sysfs file, but it is now for a different bundle than the uevent was originally for. So add the bundle class to the uevent so we "know" what the correct bundle class was.
