Subject: [PATCH AUTOSEL 4.19 02/26] dmaengine: acpi: Put the CSRT table after using it
Date: Mon, 7 Sep 2020 12:34:02 -0400 [thread overview]
Message-ID: <20200907163426.1281284-2-sashal@kernel.org> (raw)
In-Reply-To: <20200907163426.1281284-1-sashal@kernel.org>
From: Hanjun Guo <guohanjun@huawei.com>
[ Upstream commit 7eb48dd094de5fe0e216b550e73aa85257903973 ]
The acpi_get_table() should be coupled with acpi_put_table() if
the mapped table is not used at runtime to release the table
mapping, put the CSRT table buf after using it.
