Subject: [PATCH v2 4/5] ath10k:  Clean up peer when sta goes away.
Date: Fri,  1 Apr 2016 14:12:11 -0700	[thread overview]
Message-ID: <1459545132-11295-4-git-send-email-greearb@candelatech.com> (raw)
In-Reply-To: <1459545132-11295-1-git-send-email-greearb@candelatech.com>

From: Ben Greear <greearb@candelatech.com>

If WMI and/or firmware has issues removing the peer object,
then we still need to clean up the peer object in the driver.
