If anyone has any objections, please let me know. ------------------ From: Thomas Zimmermann commit f90a0e5265b60cdd3c77990e8105f79aa2fac994 upstream. Do not assing the Linux device to struct fb_info.dev. The call to register_framebuffer() initializes the field to the fbdev device. Drivers should not override its value. Fixes a bug where the driver incorrectly decreases the hardware device's reference counter and leaks the fbdev device. v2: * add Fixes tag (Dan) Signed-off-by: Thomas Zimmermann Fixes: 88017bda96a5 ("ep93xx video driver") Cc: # v2.6.32+ Reviewed-by: Javier Martinez Canillas Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20230613110953.24176-15-tzimmermann@suse.de Signed-off-by: Greg Kroah-Hartman --- drivers/video/fbdev/ep93xx-fb.c | 1 - 1 file changed, 1 deletion(-) --- a/drivers/video/fbdev/ep93xx-fb.c +++ b/drivers/video/fbdev/ep93xx-fb.c @@ -474,7 +474,6 @@ static int ep93xxfb_probe(struct platfor if (!info) return -ENOMEM; - info->dev = &pdev->dev; platform_set_drvdata(pdev, info); fbi = info->par; fbi->mach_info = mach_info;
