From 51ae796f7fa1d8034252628572053f477bc29913 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Dami=C3=A1n=20Viano?= Date: Tue, 29 Apr 2008 03:32:25 -0400 Subject: [PATCH] ACPICA: always disable GPE when requested MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit acpi_ev_disable_gpe() has an optimization where it doesn't disable a GPE that it "doesn't have to". Unfortunately, it can get tricked by AML that scribbles on register state behind its back. So when asked to disable a GPE, simply do it -- a redundant register write in the common case is a fair price to pay to be bomb-proof for the rare cases. http://bugzilla.kernel.org/show_bug.cgi?id=6217 Signed-off-by: Damián Viano Acked-by: Zhang Rui Signed-off-by: Len Brown --- drivers/acpi/events/evgpe.c | 4 ---- 1 file changed, 4 deletions(-) diff --git a/drivers/acpi/events/evgpe.c b/drivers/acpi/events/evgpe.c index 0dadd2adc800..cd06170e7871 100644 --- a/drivers/acpi/events/evgpe.c +++ b/drivers/acpi/events/evgpe.c @@ -248,10 +248,6 @@ acpi_status acpi_ev_disable_gpe(struct acpi_gpe_event_info *gpe_event_info) ACPI_FUNCTION_TRACE(ev_disable_gpe); - if (!(gpe_event_info->flags & ACPI_GPE_ENABLE_MASK)) { - return_ACPI_STATUS(AE_OK); - } - /* Make sure HW enable masks are updated */ status = -- 2.20.1
