Subject: [RFC PATCH] net: phy: Don't miss phy_suspend() on PHY_HALTED for PHYs with interrupts
Date: Wed, 15 Mar 2017 15:51:27 +0200 [thread overview]
Message-ID: <1489585887-8683-1-git-send-email-rogerq@ti.com> (raw)
Since commit 3c293f4e08b5 ("net: phy: Trigger state machine on state change and not polling.")
phy_suspend() doesn't get called as part of phy_stop() for PHYs using
interrupts because the phy state machine is never triggered after a phy_stop().
Explicitly trigger the PHY state machine so that it can
see the new PHY state (HALTED) and suspend the PHY.
