From: Giridhar Malavali <giridhar.malavali@xxxxxxxxxx> The logo ELS command allocates dma coherent memory for the data payload and serialize the completions. When this command times out, the timeout routine completes the thread waiting for completion which in turn cleanup resources allocated for this ELS command processing. Don't call generic sp->free routine when this ELS command times out to avoid to double freeing of the same resources.
