net: of_get_phy_mode: Change API to solve int/unit warnings
Before this change of_get_phy_mode() returned an enum, phy_interface_t. On error, -ENODEV etc, is returned. If the result of the function is stored in a variable of type phy_interface_t, and the compiler has decided to represent this as an unsigned int, comparision with -ENODEV etc, is a signed vs unsigned comparision. Fix this problem by changing the API. Make the function return an error, or 0 on success, and pass a pointer, of type phy_interface_t, where the phy mode should be stored. v2: Return with *interface set to PHY_INTERFACE_MODE_NA on error. Add error checks to all users of of_get_phy_mode() Fixup a few reverse christmas tree errors Fixup a few slightly malformed reverse christmas trees v3: Fix 0-day reported errors.
