Subject: ACPICA: Tables: Don't release ACPI_MTX_TABLES in acpi_tb_install_standard_table().
From: Octavian Purdila <octavian.purdila@intel.com>
commit 77ddc2fe08329e375505bc36a3df3233fe57317b upstream.
ACPICA commit c70434d4da13e65b6163c79a5aa16b40193631c7
ACPI_MTX_TABLES is acquired and released by the callers of
acpi_tb_install_standard_table() so releasing it in the function itself is
causing the following error in Linux kernel 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
