------------------ From: Burak Ok <[email protected]> [ 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. https://bugzilla.kernel.org/show_bug.cgi?id=189061 Reported-by: [email protected] Signed-off-by: Burak Ok <[email protected]> Signed-off-by: Andreas Schaertl <[email protected]> Acked-by: Narsimhulu Musini <[email protected]> Reviewed-by: Ewan D.
