Subject: [PATCH] device: make sure to remove all device units sharing the same
ecbff1
 sysfs path (#6679)
ecbff1
ecbff1
When a device is unplugged all device units sharing the same sysfs path
ecbff1
pointing to that device are supposed to be removed.
ecbff1
ecbff1
However it didn't work since while iterating the device unit list containing
ecbff1
all the relevant units, each unit was removed during each iteration of
ecbff1
LIST_FOREACH. However LIST_FOREACH doesn't support this use case and
ecbff1
LIST_FOREACH_SAFE must be use instead.
