-Subject: watchdog: da9055_wdt: Drop reference counting
-
-Reference counting is now implemented in the watchdog core and no longer
-required in watchdog drivers.
-
-Since it was implememented a no-op, and since the local memory is allocated
-with devm_kzalloc(), the reference counting code in the driver really did
-not really work anyway, and this patch effectively fixes a bug which could
-cause a crash on unloading if the watchdog device was still open.
