Hi all,

After merging the net-next tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/net/ethernet/cirrus/cs89x0.c: In function 'net_open':
drivers/net/ethernet/cirrus/cs89x0.c:897:20: error: implicit declaration of function 'isa_virt_to_bus' [-Werror=implicit-function-declaration]

      |   ^~~~~~~~

Caused by commit

  47fd22f2b847 ("cs89x0: rework driver configuration")

I have removed the COMPILE_TEST from NET_VENDOR_CIRRUS for now.
