Subject: [Intel-wired-lan] [PATCH 04/19] igc: Early return in igc_get_ethtool_nfc_entry()
Date: Fri, 24 Apr 2020 13:16:08 -0700 [thread overview]
Message-ID: <20200424201623.10971-5-andre.guedes@intel.com> (raw)
In-Reply-To: <20200424201623.10971-1-andre.guedes@intel.com>
This patch re-writes the second half of igc_ethtool_get_nfc_entry() to
follow the 'return early' pattern seen in other parts of the driver and
removes some duplicate comments.
