Ly" Date: Tue, 9 May 2017 11:50:26 -0500 Subject: ibmvscsis: Clear left-over abort_cmd pointers From: Bryant G. Ly commit 98883f1b5415ea9dce60d5178877d15f4faa10b8 upstream. With the addition of ibmvscsis->abort_cmd pointer within commit 25e78531268e ("ibmvscsis: Do not send aborted task response"), make sure to explicitly NULL these pointers when clearing DELAY_SEND flag. Do this for two cases, when getting the new new ibmvscsis descriptor in ibmvscsis_get_free_cmd() and before posting the response completion in ibmvscsis_send_messages(). Signed-off-by: Bryant G.
