I have no clue about the nios2, so not sure if this is an arch-specific
linker error or not.
Hmm but the .config has the following:
CONFIG_TYPEC_UCSI=y
CONFIG_USB_ROLE_SWITCH=m
So I'm guessing this patch also requires a Kconfig change to disallow
the above combination? If so, should UCSI have a "depends" or a
"select"
on USB_ROLE_SWITCH?

Hm, there is certainly a mixture of depends and selects in the kernel source
tree. I would say "depends", based on
Documentation/kbuild/kconfig-language.rst:
("->" added for emphasis)
Note:
select should be used with care. select will force
a symbol to a value without visiting the dependencies.
By abusing select you are able to select a symbol FOO even
if FOO depends on BAR that is not set.
-> In general use select only for non-visible symbols
-> (no prompts anywhere) and for symbols with no dependencies.
That will limit the usefulness but on the other hand avoid
the illegal configurations all over.

CONFIG_TYPEC_UCSI=y
CONFIG_USB_ROLE_SWITCH=m
So I'm guessing this patch also requires a Kconfig change to disallow
the above combination? If so, should UCSI have a "depends" or a
"select"
on USB_ROLE_SWITCH?
Kconfig needs to prevent the UCSI driver from being built-in when the
USB Role Switch Class is being build as module. That can be achieved
with this trick (it's not ideal, but it works):
depends on USB_ROLE_SWITCH || !USB_ROLE_SWITCH
I'll send the fix.
