Move marking the PHY as being on a SFP module into the SFP code between getting the PHY device (and thus initialising the phy_device structure) and registering the discovered device. This means that PHY drivers can use phy_on_sfp() in their match and get_features methods. Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> --- Eric Woudstra has a SFP module that has a realtek PHY on that could be driven by the realtek PHY driver - except that the PHY is behind a Rollball access implementation that only supports clause 45 access. This is a work in progress, but it seems useful in these situations that drivers should know whether the PHY is on a module very early on, so that a particular PHY driver instance can choose whether or not to drive the instance, or maybe use a different PHY driver instance to drive it - thus allowing a separate set of function pointers for the clause-45 only accessable PHY. Some experimental patches can be found at: https://gist.github.com/ericwoud/d912301a93cd41b39621a65cc372a5c0#file-0000-oem-sfp-2-5g-t-patches-realtek-short-c and onward discussion prompted this patch.
