-Subject: powerpc/eeh: Clear stale EEH_DEV_NO_HANDLER flag
-
-From: Sam Bobroff <sbobroff@linux.ibm.com>
-
-[ Upstream commit aa06e3d60e245284d1e55497eb3108828092818d ]
-
-The EEH_DEV_NO_HANDLER flag is used by the EEH system to prevent the
-use of driver callbacks in drivers that have been bound part way
-through the recovery process. This is necessary to prevent later stage
-handlers from being called when the earlier stage handlers haven't,
-which can be confusing for drivers.
-
-However, the flag is set for all devices that are added after boot
-time and only cleared at the end of the EEH recovery process. This
-results in hot plugged devices erroneously having the flag set during
-the first recovery after they are added (causing their driver's
-handlers to be incorrectly ignored).
-
-To remedy this, clear the flag at the beginning of recovery
-processing. The flag is still cleared at the end of recovery
-processing, although it is no longer really necessary.
-
-Also clear the flag during eeh_handle_special_event(), for the same
-reasons.
