[Greg Kroah-Hartman]

From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

[ Upstream commit 4c09f8b6913a779ca0c70ea8058bf21537eebb3b ]

Fix to return negative error code -ENOMEM from the kvcalloc() error
handling case instead of 0, as done elsewhere in this function.

Fixes: acdf52d97f82 ("selinux: convert to kvmalloc")
