Subject: [PATCH v2 1/5] ath10k:  Ensure txrx-compl-task is stopped when cleaning htt-tx.
Date: Fri,  1 Apr 2016 14:12:08 -0700	[thread overview]
Message-ID: <1459545132-11295-1-git-send-email-greearb@candelatech.com> (raw)

From: Ben Greear <greearb@candelatech.com>

Otherwise, the txrx-compl-task may access some bad memory?
