Subject: [PATCH 2/3] net/nfp: fix the reconfigure logic in VF initialization
Date: Sat, 28 Oct 2023 14:23:14 +0800	[thread overview]
Message-ID: <20231028062315.1843075-3-chaoyong.he@corigine.com> (raw)
In-Reply-To: <20231028062315.1843075-1-chaoyong.he@corigine.com>

There exists exit point between the reconfigure logic and the stroe
logic of the VF initialization, this may lead one situation that value
in the config bar is not same with the value stored in the data
structure.

Fix this by move up the store statement.

Fixes: 7f8e73201dae ("net/nfp: move VF functions into its own file")
