Subject: [PATCH] keys: asymmetric: fix error return code in software_key_query()
Date: Wed, 15 Jul 2020 22:28:38 +0000	[thread overview]
Message-ID: <159485211858.2340757.9890754969922775496.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <20200622112136.72745-1-weiyongjun1@huawei.com>

From: Wei Yongjun <weiyongjun1@huawei.com>

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

Fixes: f1774cb8956a ("X.509: parse public key parameters from x509 for akcipher")
