Kees Cook 842803e4a6 video: uvesafb: Fix integer overflow in allocation 
commit 9f645bcc56 upstream.

cmap->len can get close to INT_MAX/2, allowing for an integer overflow in
allocation. This uses kmalloc_array() instead to catch the condition.

Reported-by: Dr Silvio Cesare of InfoSect <silvio.cesare@gmail.com>
Fixes: 8bdb3a2d7d ("uvesafb: the driver core")
