Subject: [PATCH] can: ctucanfd: Remove a useless netif_napi_del() call
Date:   Thu, 18 May 2023 09:10:39 +0200
Message-Id: <58500052a6740806e8af199ece45e97cb5eeb1b8.1684393811.git.christophe.jaillet@wanadoo.fr>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

free_candev() already calls netif_napi_del(), so there is no need to call
it explicitly. It is harmless, but useless.

This makes the code mode consistent with the error handling path of
ctucan_probe_common().

While at it, remove a wrong comment about the return value of this
function.
