Subject: [PATCH 07/16] block: sed-opal: unify error handling of responses
Date: Thu, 14 Feb 2019 01:15:59 +0100 [thread overview]
Message-ID: <1550103368-4605-8-git-send-email-zub@linux.fjfi.cvut.cz> (raw)
In-Reply-To: <1550103368-4605-1-git-send-email-zub@linux.fjfi.cvut.cz>
response_get_{string,u64} include error handling for argument resp being
NULL but response_get_token does not handle this.
Make all three of response_get_{string,u64,token} handle NULL resp in
the same way.
