CVE-2022-50389

In the Linux kernel, the following vulnerability has been resolved: tpm: tpm_crb: Add the missed acpi_put_table() to fix memory leak In crb_acpi_add(), we get the TPM2 table to retrieve information like start method, and then assign them to the priv data, so the TPM2 table is not used after the init, should be freed, call acpi_put_table() to fix the memory leak.
