Anyway imho this time gcc got it right?

blockdev: bd_claim_by_kobject() could check value of unititalized pointer
Fixes this warning:
fs/block_dev.c: In function `bd_claim_by_kobject':
fs/block_dev.c:953: warning: 'found' might be used uninitialized in this
function
struct bd_holder *found is initialized only when bd_claim() returns zero. If it
returns nonzero, ptr stays uninitialized. Later the value of the pointer is
checked.
