Subject: [PATCH AUTOSEL 5.4 25/37] habanalabs: Call put_pid() when releasing control device
Date: Tue, 16 Mar 2021 20:57:50 -0400 [thread overview]
Message-ID: <20210317005802.725825-25-sashal@kernel.org> (raw)
In-Reply-To: <20210317005802.725825-1-sashal@kernel.org>
From: Tomer Tayar <ttayar@habana.ai>
[ Upstream commit 27ac5aada024e0821c86540ad18f37edadd77d5e ]
The refcount of the "hl_fpriv" structure is not used for the control
device, and thus hl_hpriv_put() is not called when releasing this
device.
This results with no call to put_pid(), so add it explicitly in
hl_device_release_ctrl().
