Dan Carpenter 4ea3913b19 fbdev: potential information leak in do_fb_ioctl() 
commit d3d19d6fc5 upstream.

The "fix" struct has a 2 byte hole after ->ywrapstep and the
"fix = info->fix;" assignment doesn't necessarily clear it.  It depends
on the compiler.  The solution is just to replace the assignment with an
memcpy().

Fixes: 1f5e31d7e5 ("fbmem: don't call copy_from/to_user() with mutex held")
