Subject: [PATCH v2 06/11] net/nfp: remove redundancy logic of init control BAR
Date: Sat, 28 Oct 2023 14:53:10 +0800 [thread overview]
Message-ID: <20231028065315.1937188-7-chaoyong.he@corigine.com> (raw)
In-Reply-To: <20231028065315.1937188-1-chaoyong.he@corigine.com>
There are two initialize statements of control BAR in 'nfp_net_init()'
and the first one is unneeded, and what it really use is the check of
NULL value of the 'mem_resource'. So we move the check of 'mem_resource'
to the start of probe logic.
