From: Felipe F. Tonello eu@felipetonello.com
commit 69bb99738b5c6d56d2b1a75db9cbb4d187453c1a upstream.
Length of buffers should be of type size_t whenever possible. Altough recommended, this change has no real practical change, unless a driver has a uses a huge or negative buffer size - it might help find these bugs.
