2.6.32-stable review patch. If anyone has any objections, please let us know. ------------------ From: Uwe Kleine-König commit 1ec562035ba64e724652cb12b8a770b3906e9bf5 upstream. 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 Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman --- drivers/video/imxfb.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) --- a/drivers/video/imxfb.c +++ b/drivers/video/imxfb.c @@ -593,7 +593,8 @@ static int imxfb_activate_var(struct fb_ */ 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 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__);
