The command miiphy_read(name, 0xEE, 0xEE, (u16 *) &devadr) always returns 8 for the PHY address. It is the reset value for the PHY Address Register. Obviously, this default value could be incorrect. Moreover, as the PHY address is well known, there is no need to auto-detect it. Now, the PHY address must given as a parameter to the PHY initialization function. Additionally this patch also fixes some aesthetic issues. Signed-off-by: Simon Guinot <simon.guinot@sequanux.org>
