Subject: [PATCH] dmaengine: acpi: Put the CSRT table after using it
Git-commit: 7eb48dd094de5fe0e216b550e73aa85257903973
Patch-mainline: v5.9-rc4

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.
