[PATCH 0/2] Fix pci_iounmap() on !CONFIG_GENERIC_IOMAP

From: Lorenzo Pieralisi
Date: Tue Sep 15 2020 - 05:32:16 EST


Fix the empty pci_iounmap() implementation that is causing memory leaks on
!CONFIG_GENERIC_IOMAP configs relying on asm-generic/io.h.

A small tweak is required on sparc32 to pull in some declarations,
hopefully nothing problematic, subject to changes as requested.
