It looks like the series has been pushed to git.kernel.org now.
I have tested the reversion of commit 92a8046c9d952a and can confirm
that the ISA_BUS_API dependency / selection for gpio-winbond works
then as intended (in a way that is consistent with other ISA bus gpio
drivers).

@Linus:
Will you revert that commit or should I submit a patch that does it?
