Subject: [PATCH v2 net-next] net: phy: fixed_phy: Fix fixed_phy not checking GPIO
Date: Wed, 6 Feb 2019 21:45:29 -0800 [thread overview]
Message-ID: <20190207054529.2865-1-mdf@kernel.org> (raw)
Fix fixed_phy not checking GPIO if no link_update callback
is registered.
In the original version all users registered a link_update
callback so the issue was masked.
Fixes: a5597008dbc2 ("phy: fixed_phy: Add gpio to determine link up/down.")
Reviewed-by: Andrew Lunn <andrew@lunn.ch>
Signed-off-by: Moritz Fischer <mdf@kernel.org>
