linux-next: build failure after merge of the powerpc-fixes tree

Hi all,

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

drivers/net/ethernet/ibm/ibmvnic.c:5399:13: error: conflicting types for 'ibmvnic_remove'
 5399 | static void ibmvnic_remove(struct vio_dev *dev)
      |             ^~~~~~~~~~~~~~
drivers/net/ethernet/ibm/ibmvnic.c:81:12: note: previous declaration of 'ibmvnic_remove' was here
   81 | static int ibmvnic_remove(struct vio_dev *);
      |            ^~~~~~~~~~~~~~

Caused by commit

  1bdd1e6f9320 ("vio: make remove callback return void")

I have applied the following patch for today:

Gah, is IBMVNIC in any of our defconfigs?! ... no it's not.

Thanks, I'll squash it in.

Would you accept a patch to add the driver to one of the defconfigs as 
an excuse for the build breakage I created? Which would be appropriate? 
ppc64_defconfig?

Also thanks for catching to Stephen and to Michael for the fixup.

Best regards

Thanks, but I already sent a patch adding it.

We should really have these drivers enabled in our defconfig, so that's
on us.

cheers
