Subject: [PATCH] firmware: arm_sdei: Put the SDEI table after using it
Date: Sat, 9 May 2020 18:52:46 +0800 [thread overview]
Message-ID: <1589021566-46373-1-git-send-email-guohanjun@huawei.com> (raw)
The acpi_get_table() should be coupled with acpi_put_table() if
the mapped table is not used for runtime after the initialization
to release the table mapping, put the SDEI table after using it.
