From 1ec562035ba64e724652cb12b8a770b3906e9bf5 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Tue, 2 Feb 2010 13:44:10 -0800 Subject: imxfb: correct location of callbacks in suspend and resume MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The probe function passes a pointer to a struct fb_info to platform_set_drvdata(), so don't interpret the return value of platform_get_drvdata() as a pointer to struct imxfb_info. The original imxfb_info *fbi backlight_power was NULL but in imxfb_suspend it was 4 resulting in an oops as imxfb_suspend calls imxfb_disable_controller(fbi) which in turn has if (fbi->backlight_power) fbi->backlight_power(0); Signed-off-by: Uwe Kleine-König Acked-by: Sascha Hauer Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/video/imxfb.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'drivers/video/imxfb.c') diff --git a/drivers/video/imxfb.c b/drivers/video/imxfb.c index 66358fa825f3..b4b6deceed15 100644 --- a/drivers/video/imxfb.c +++ b/drivers/video/imxfb.c @@ -593,7 +593,8 @@ static int imxfb_activate_var(struct fb_var_screeninfo *var, struct fb_info *inf */ static int imxfb_suspend(struct platform_device *dev, pm_message_t state) { - struct imxfb_info *fbi = platform_get_drvdata(dev); + struct fb_info *info = platform_get_drvdata(dev); + struct imxfb_info *fbi = info->par; pr_debug("%s\n", __func__); @@ -603,7 +604,8 @@ static int imxfb_suspend(struct platform_device *dev, pm_message_t state) static int imxfb_resume(struct platform_device *dev) { - struct imxfb_info *fbi = platform_get_drvdata(dev); + struct fb_info *info = platform_get_drvdata(dev); + struct imxfb_info *fbi = info->par; pr_debug("%s\n", __func__); -- cgit v1.2.3
