Subject: [net-next 15/17] e1000e: Warn if disabling ULP failed
Date: Fri, 22 May 2020 19:51:07 -0700 [thread overview]
Message-ID: <20200523025109.3313635-16-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20200523025109.3313635-1-jeffrey.t.kirsher@intel.com>
From: Kai-Heng Feng <kai.heng.feng@canonical.com>
The hardware may stop working if driver failed to disable ULP mode.
Take the return value of e1000_disable_ulp_lpt_lp() into account, and
pass up the error if it fails.
