X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6fe3264945ee63292cdfb27b6e95bc52c603bb09;p=linux-beck.git netdev/phy: Use mdiobus_read() so that proper locks are taken. Accesses to the mdio busses must be done with the mdio_lock to ensure proper operation. Conveniently we have the helper function mdiobus_read() to do that for us. Lets use it in get_phy_id() instead of accessing the bus without the lock held. Signed-off-by: David Daney Signed-off-by: David S.
