Subject: [PATCH] snic: Return error code on memory allocation failure
Date: Wed, 21 Dec 2016 14:45:53 +0100 [thread overview]
Message-ID: <1482327953-4140-1-git-send-email-burak-kernel@bur0k.de> (raw)
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.
