In the function *_set_par(), the value of 'screen_size' is calculated by the user input. If the user provides the improper value, the value of 'screen_size' may larger than 'info->screen_size', which may cause a bug in the memset_io(). Zheyu Ma (3): video: fbdev: vt8623fb: Check the size of screen before memset_io() video: fbdev: arkfb: Check the size of screen before memset_io() video: fbdev: s3fb: Check the size of screen before memset_io()
applied all 3 patches to fbdev git tree. Thanks! Helge
