[PATCH] Fix memory leak in vc_resize/vc_allocate
Memory leaks can happen in the vc_resize() function in drivers/char/vt.c
because of the vc->vc_screenbuf variable overriding in vc_allocate(). The
kmemleak reported trace is as follows:
<__kmalloc>
<vc_resize>
<fbcon_init>
<visual_init>
<vc_allocate>
<con_open>
<tty_open>
<chrdev_open>
This patch no longer allocates a screen buffer in vc_allocate() if it was
already allocated by vc_resize().
