In the Linux kernel, the following vulnerability has been resolved: fbdev/ep93xx-fb: Do not assign to struct fb_info.dev 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)
