Subject: [PATCH 5.12 328/700] ACPI: tables: FPDT: Add missing acpi_put_table() in acpi_init_fpdt()

From: Jing Xiangfeng <jingxiangfeng@...wei.com>

[ Upstream commit dd9eaa23e72572d4f1c03f2e5d2e14a5b5793e79 ]

acpi_init_fpdt() forgets to call acpi_put_table() in an error path.

Add the missing function call to fix it.

Fixes: d1eb86e59be0 ("ACPI: tables: introduce support for FPDT table")
