Subject: [PATCH AUTOSEL 5.13 047/219] media: atomisp: Fix runtime PM imbalance in atomisp_pci_probe
Date: Thu,  9 Sep 2021 07:43:43 -0400	[thread overview]
Message-ID: <20210909114635.143983-47-sashal@kernel.org> (raw)
In-Reply-To: <20210909114635.143983-1-sashal@kernel.org>

From: Dinghao Liu <dinghao.liu@zju.edu.cn>

[ Upstream commit 672fe1cf145ab9978c62eb827d6a16aa6b63994b ]

When hmm_pool_register() fails, a pairing PM usage counter
increment is needed to keep the counter balanced. It's the
same for the following error paths.
