Subject: net: llc: use correct size for sysctl timeout entries
From: Sasha Levin <sasha.levin@xxxxxxxxxx>
commit 6b8d9117ccb4f81b1244aafa7bc70ef8fa45fc49 upstream.
The timeout entries are sizeof(int) rather than sizeof(long), which
means that when they were getting read we'd also leak kernel memory
to userspace along with the timeout values.
