Subject: [PATCH 1/3] crypto: digest: Return -errno if open() fails
Date: Wed, 16 Jan 2019 20:45:04 -0800	[thread overview]
Message-ID: <20190117044506.20628-1-andrew.smirnov@gmail.com> (raw)

Strictly speaking, open() doesn't return a detailed error code as its
return value and it can and should be obtained via 'errno'.
