Subject: [PATCH v5 1/5] net: macb: fix wakeup test in runtime suspend/resume routines
Date: Fri, 10 Jul 2020 14:46:41 +0200 [thread overview]
Message-ID: <ca0f11de3b574c293fa79e01e4eb31514b6c7233.1594384335.git.nicolas.ferre@microchip.com> (raw)
In-Reply-To: <cover.1594384335.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: d54f89af6cc4 ("net: macb: Add pm runtime support")
