net: phy: make phy_error() report which PHY has failed
phy_error() is called from phy_interrupt() or phy_state_machine(), and uses WARN_ON() to print a backtrace. The backtrace is not useful when reporting a PHY error. However, a system may contain multiple ethernet PHYs, and phy_error() gives no clue which one caused the problem. Replace WARN_ON() with a call to phydev_err() so that we can see which PHY had an error, and also inform the user that we are halting the PHY. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
