Dave Jiang a01c0c1600 dmaengine: ioat: stop mod_timer from resurrecting deleted timer in __cleanup() ... [ Upstream commit 898ec89dbb55b8294695ad71694a0684e62b2a73 ] User reports observing timer event report channel halted but no error observed in CHANERR register. The driver finished self-test and released channel resources. Debug shows that __cleanup() can call mod_timer() after the timer has been deleted and thus resurrect the timer. While harmless, it causes suprious error message to be emitted. Use mod_timer_pending() call to prevent deleted timer from being resurrected.
