My build tests failed to catch that amba driver that would have needed
adaption in commit 3fd269e74f2f ("amba: Make the remove callback return
void"). Change the remove function to make the driver build again.

Hello,

I guess I missed that driver during rebase as it was only introduced in
the last merge window. Sorry for that.

I'm unsure what is the right thing to do now. Should I redo the pull
request (with this patch squashed into 3fd269e74f2f)? Or do we just
apply this patch on top?

FTR, the test robot report is at https://lore.kernel.org/r/202102030343.D9j1wukx-lkp@intel.com

Best regards
Uwe
