From a60b21763cce01c64cc537869662b41429c62e5f Mon Sep 17 00:00:00 2001 From: Corentin Chary Date: Wed, 13 Jun 2012 09:32:02 +0200 Subject: [PATCH] drivers-platform-x86: use acpi_video_dmi_promote_vendor() Instead of using directly acpi_video_unregister(), use acpi_video_dmi_promote_vendor() (and make it call acpi_video_unregister() if needed) Signed-off-by: Corentin Chary Signed-off-by: Matthew Garrett --- drivers/platform/x86/acer-wmi.c | 16 +++++++++------- drivers/platform/x86/apple-gmux.c | 6 ++++++ drivers/platform/x86/samsung-laptop.c | 22 ++++++++++++---------- 3 files changed, 27 insertions(+), 17 deletions(-) diff --git a/drivers/platform/x86/acer-wmi.c b/drivers/platform/x86/acer-wmi.c index 175809dd5587..377d92d8d9b1 100644 --- a/drivers/platform/x86/acer-wmi.c +++ b/drivers/platform/x86/acer-wmi.c @@ -2191,14 +2191,16 @@ static int __init acer_wmi_init(void) set_quirks(); + if (dmi_check_system(video_vendor_dmi_table)) + acpi_video_dmi_promote_vendor(); if (acpi_video_backlight_support()) { - if (dmi_check_system(video_vendor_dmi_table)) { - acpi_video_unregister(); - } else { - interface->capability &= ~ACER_CAP_BRIGHTNESS; - pr_info("Brightness must be controlled by " - "acpi video driver\n"); - } + interface->capability &= ~ACER_CAP_BRIGHTNESS; + pr_info("Brightness must be controlled by acpi video driver\n"); + } else { +#ifdef CONFIG_ACPI_VIDEO + pr_info("Disabling ACPI video driver\n"); + acpi_video_unregister(); +#endif } if (wmi_has_guid(WMID_GUID3)) { diff --git a/drivers/platform/x86/apple-gmux.c b/drivers/platform/x86/apple-gmux.c index 694a15a56230..905fa01ac8df 100644 --- a/drivers/platform/x86/apple-gmux.c +++ b/drivers/platform/x86/apple-gmux.c @@ -193,7 +193,10 @@ static int __devinit gmux_probe(struct pnp_dev *pnp, * backlight control and supports more levels than other options. * Disable the other backlight choices. */ + acpi_video_dmi_promote_vendor(); +#ifdef CONFIG_ACPI_VIDEO acpi_video_unregister(); +#endif apple_bl_unregister(); return 0; @@ -213,7 +216,10 @@ static void __devexit gmux_remove(struct pnp_dev *pnp) release_region(gmux_data->iostart, gmux_data->iolen); kfree(gmux_data); + acpi_video_dmi_demote_vendor(); +#ifdef CONFIG_ACPI_VIDEO acpi_video_register(); +#endif apple_bl_register(); } diff --git a/drivers/platform/x86/samsung-laptop.c b/drivers/platform/x86/samsung-laptop.c index e2a34b42ddc1..2cbccc1b4b68 100644 --- a/drivers/platform/x86/samsung-laptop.c +++ b/drivers/platform/x86/samsung-laptop.c @@ -26,7 +26,7 @@ #include #include #include -#if (defined CONFIG_ACPI_VIDEO || defined CONFIG_ACPI_VIDEO_MODULE) +#ifdef CONFIG_ACPI_VIDEO #include #endif @@ -1530,15 +1530,18 @@ static int __init samsung_init(void) samsung->quirks = quirks; -#if (defined CONFIG_ACPI_VIDEO || defined CONFIG_ACPI_VIDEO_MODULE) +#ifdef CONFIG_ACPI + if (samsung->quirks->broken_acpi_video) + acpi_video_dmi_promote_vendor(); + /* Don't handle backlight here if the acpi video already handle it */ if (acpi_video_backlight_support()) { - if (samsung->quirks->broken_acpi_video) { - pr_info("Disabling ACPI video driver\n"); - acpi_video_unregister(); - } else { - samsung->handle_backlight = false; - } + samsung->handle_backlight = false; + } else if (samsung->quirks->broken_acpi_video) { + pr_info("Disabling ACPI video driver\n"); +#ifdef CONFIG_ACPI_VIDEO + acpi_video_unregister(); +#endif } #endif @@ -1552,8 +1555,7 @@ static int __init samsung_init(void) #ifdef CONFIG_ACPI /* Only log that if we are really on a sabi platform */ - if (acpi_video_backlight_support() && - !samsung->quirks->broken_acpi_video) + if (acpi_video_backlight_support()) pr_info("Backlight controlled by ACPI video driver\n"); #endif -- 2.20.1
