Greetings,

0day kernel testing robot got the below dmesg and the first bad commit is

git://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git master

commit 3a2c0ba5ad00c018c0bef39a2224aca950aa33f2
Author:     Rusty Russell <ru...@rustcorp.com.au>
AuthorDate: Mon Dec 8 16:50:37 2014 +0800
Commit:     Herbert Xu <herb...@gondor.apana.org.au>
CommitDate: Mon Dec 22 23:02:39 2014 +1100

    hwrng: use reference counts on each struct hwrng.
    
    current_rng holds one reference, and we bump it every time we want
    to do a read from it.
    
    This means we only hold the rng_mutex to grab or drop a reference,
    so accessing /sys/devices/virtual/misc/hw_random/rng_current doesn't
    block on read of /dev/hwrng.
    
    Using a kref is overkill (we're always under the rng_mutex), but
    a standard pattern.
    
    This also solves the problem that the hwrng_fillfn thread was
    accessing current_rng without a lock, which could change (eg. to NULL)
    underneath it.
