Subject: [PATCH 1/5] net: macb: fix wakeup test in runtime suspend/resume routines
Date: Thu, 16 Apr 2020 19:44:28 +0200 [thread overview]
Message-ID: <eba7f3605d6dcad37f875b2584d519cd6cae9fd1.1587058078.git.nicolas.ferre@microchip.com> (raw)
In-Reply-To: <cover.1587058078.git.nicolas.ferre@microchip.com>
From: Nicolas Ferre <nicolas.ferre@microchip.com>
Use the proper struct device pointer to check if the wakeup flag
and wakeup source are positioned.
Use the one passed by function call which is equivalent to
&bp->dev->dev.parent.
It's preventing the trigger of a spurious interrupt in case the
Wake-on-Lan feature is used.
Fixes: bc1109d04c39 ("net: macb: Add pm runtime support")
