Subject: [PATCH 0/3] Fix bugs in *_set_par() caused by user input

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().
