Subject: [PATCH v2 4/6] qla2xxx: Suppress Coverity complaints about dseg_r*
Date: Wed, 17 Mar 2021 20:28:38 -0700	[thread overview]
Message-ID: <20210318032840.7611-5-bvanassche@acm.org> (raw)
In-Reply-To: <20210318032840.7611-1-bvanassche@acm.org>

Change dseq_rq and dseg_rsp from scalar structure members into
single-element arrays such that Coverity does not complain about the
(*cur_dsd)++ statement in append_dsd64().
