X-Git-Tag: upstream/snapshot3+hdmi~11659^2~5

ACPICA: Fix memory leak in acpi_ev_asynch_execute_gpe_method().

We will leak the memory allocated to 'local_gpe_event_info' if
'acpi_ut_acquire_mutex()' fails or if 'acpi_ev_valid_gpe_event()' fails in
drivers/acpi/acpica/evgpe.c::acpi_ev_asynch_execute_gpe_method().
