| |
ACPI_MTX_TABLES is taken and released by the callers of acpi_tb_install_standard_table so releasing it in the function itself is causing the following error if the table is reloaded:
ACPI Error: Mutex [0x2] is not acquired, cannot release (20141107/utmutex-321) Call Trace: [<ffffffff81b0bd48>] dump_stack+0x4f/0x7b [<ffffffff81546bf5>] acpi_ut_release_mutex+0x47/0x67 [<ffffffff81544357>] acpi_load_table+0x73/0xcb
