ACPICA: Tables: Don't release ACPI_MTX_TABLES in acpi_tb_install_standard_table().
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 Link: https://github.com/acpica/acpica/commit/c70434d4 Signed-off-by: Octavian Purdila <octavian.purdila@intel.com> Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Cc: 3.16+ <stable@vger.kernel.org> # 3.16+ Signed-off-by: Rafael J.
