Subject: [PATCH] staging: fsl-dpaa2/ethsw: fix memory leak of switchdev_work
Date: Sat, 8 Jun 2019 12:50:31 +0100 [thread overview]
Message-ID: <20190608115031.28126-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
In the default event case switchdev_work is being leaked because
nothing is queued for work. Fix this by kfree'ing switchdev_work
before returning NOTIFY_DONE.
Addresses-Coverity: ("Resource leak")
Fixes: 44baaa43d7cc ("staging: fsl-dpaa2/ethsw: Add Freescale DPAA2 Ethernet Switch driver")
