The get_mac_address() function is normally inline, but when it is
not, we get a warning that this configuration is broken:

WARNING: vmlinux.o(.text+0x4aff00): Section mismatch in reference from the function w90p910_ether_setup() to the function .init.text:get_mac_address()
The function w90p910_ether_setup() references
the function __init get_mac_address().
This is often because w90p910_ether_setup lacks a __init

Remove the __init to make it always do the right thing.

Actually I think we can validly mark w90p910_ether_setup() and
w90p910_probe() with appropriate init tagging.  None of these
functions are invoked outside of the probing paths.

But then we have to change the driver to use
module_platform_driver_probe(), to ensure we cannot
unbind/rebind the device. I usually don't like doing that,
unless the device can never be stopped after it has
been initialized.

Fair enough, let's go with your simpler fix for now.

Applied.
