Subject: [PATCH] VFS: initlalise found in fs/block_dev.c:bd_claim_by_kobject()

The patch below fixes the following warning, which
by my reckoning is valid, though perhaps not
something that happens in practice.

fs/block_dev.c: In function `bd_claim_by_disk':
fs/block_dev.c:953: warning: 'found' might be used uninitialized in this
function

Patch is against the current Linus tree,
33e563c1190c26b6bf61990c505cdcb5cdbba7e4. 2.6.20+
