Subject: [PATCH 3/3] net: phy: xgmiitorgmii: Check read_status results
Date: Thu,  7 Jun 2018 10:53:48 -0500	[thread overview]
Message-ID: <20180607155348.149665-3-brandon.maier@rockwellcollins.com> (raw)
In-Reply-To: <20180607155348.149665-1-brandon.maier@rockwellcollins.com>

We're ignoring the result of the attached phy device's read_status().
Return it so we can detect errors.
