Subject: [PATCH net-next v2 04/11] bnxt_en: devlink health: use retained error fmsg API
Date:   Tue, 17 Oct 2023 12:53:34 +0200
Message-Id: <20231017105341.415466-5-przemyslaw.kitszel@intel.com>
In-Reply-To: <20231017105341.415466-1-przemyslaw.kitszel@intel.com>
References: <20231017105341.415466-1-przemyslaw.kitszel@intel.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Drop unneeded error checking.

devlink_fmsg_*() family of functions is now retaining errors,
so there is no need to check for them after each call.
