From af96f87703f33a4dba4b51c7b3f0d6f874aa4853 Mon Sep 17 00:00:00 2001 From: Corentin Chary Date: Sun, 6 Feb 2011 13:27:30 +0100 Subject: [PATCH] asus-laptop: let WLED alone on L1400B Asus took the DSDT from another model (L84F), made some change to make it work, but forgot to remove WLED method (the laptop doesn't have a wireless card). They even didn't change the model name. ref: https://bugzilla.kernel.org/show_bug.cgi?id=25712 Signed-off-by: Corentin Chary Signed-off-by: Matthew Garrett --- drivers/platform/x86/asus-laptop.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) diff --git a/drivers/platform/x86/asus-laptop.c b/drivers/platform/x86/asus-laptop.c index 5a6f7d7575d6..2b9d7b8636e3 100644 --- a/drivers/platform/x86/asus-laptop.c +++ b/drivers/platform/x86/asus-laptop.c @@ -50,6 +50,7 @@ #include #include #include +#include #include #include @@ -1557,6 +1558,20 @@ static int __devinit asus_acpi_init(struct asus_laptop *asus) return result; } +static void __devinit asus_dmi_check(void) +{ + const char *model; + + model = dmi_get_system_info(DMI_PRODUCT_NAME); + if (!model) + return; + + /* On L1400B WLED control the sound card, don't mess with it ... */ + if (strncmp(model, "L1400B", 6) == 0) { + wlan_status = -1; + } +} + static bool asus_device_present; static int __devinit asus_acpi_add(struct acpi_device *device) @@ -1575,6 +1590,8 @@ static int __devinit asus_acpi_add(struct acpi_device *device) device->driver_data = asus; asus->device = device; + asus_dmi_check(); + result = asus_acpi_init(asus); if (result) goto fail_platform; -- 2.34.1
