786c4a5372 net: phy: dp83869: Fix return paths to return proper values 
Fix the return paths for all I/O operations to ensure
that the I/O completed successfully.  Then pass the return
to the caller for further processing

c21709e744 net: phy: dp83869: fix return of uninitialized variable ret 
In the case where the call to phy_interface_is_rgmii returns zero
the variable ret is left uninitialized and this is returned at
the end of the function dp83869_configure_rgmii.  Fix this by
returning 0 instead of the uninitialized value in ret.

Addresses-Coverity: ("Uninitialized scalar variable")
