Commit 0b50dc4f ("Convert smsc911x to use ACPI as well as DT") makes the call to smsc911x_probe_config() unconditional, and no longer fails if there is no device node. device_get_phy_mode() is called unconditionally, and if there is no phy node configured returns an error code. This error code is assigned to phy_interface, and interpreted elsewhere in the code as valid phy mode. This in turn causes qemu to crash when running a variant of realview_pb_defconfig. qemu: hardware error: lan9118_read: Bad reg 0x86 Fixes: 0b50dc4f ("Convert smsc911x to use ACPI as well as DT") Cc: Jeremy Linton <jeremy.linton@arm.com> Cc Graeme Gregory <graeme.gregory@linaro.org> Signed-off-by:
