[PATCH] net: macb: Add default usrio config to default gem config

[PATCH] net: macb: Add default usrio config to default gem config

[Atish Patra]

There is no usrio config defined for default gem config leading to
a kernel panic devices that don't define a data. This issue can be
reprdouced with microchip polar fire soc where compatible string
is defined as "cdns,macb".

Fixes: edac63861db7 ("add userio bits as platform configuration")

Fixes tag needs work:

Fixes tag: Fixes: edac63861db7 ("add userio bits as platform configuration")
Has these problem(s):
	- empty line after the tag
	- Subject does not match target commit subject
	  Just use
		git log -1 --format='Fixes: %h ("%s")'

Please put [PATCH net] as subject prefix, to indicate this 
is a networking fix.

You can also CC Andrew Lunn like get_maintainer.pl suggests,
but drop linux-kernel from the CC/To.
