Subject: [PATCH 06/16] block: sed-opal: unify error handling of responses
Date: Thu, 15 Nov 2018 21:33:33 +0100 [thread overview]
Message-ID: <20190116225540.470186004E@linux.fjfi.cvut.cz> (raw)
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.
