Description

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: Add the missed acpi_put_table() to fix memory leak When the radeon driver reads the bios information from ACPI table in radeon_acpi_vfct_bios(), it misses to call acpi_put_table() to release the ACPI memory after the init, so add acpi_put_table() properly to fix the memory leak. v2: fix text formatting (Alex)
