Subject: scsi: snic: Return error code on memory allocation failure
From: Burak Ok <burak-kernel@bur0k.de>
[ Upstream commit 0371adcdaca92912baaa3256ed13e058a016e62d ]
If a call to mempool_create_slab_pool() in snic_probe() returns NULL,
return -ENOMEM to indicate failure. mempool_creat_slab_pool() only fails
if it cannot allocate memory.
