Subject: [PATCH 5.10 09/29] sparc64: fix pci_iounmap() when CONFIG_PCI is not set
Date: Fri, 8 Oct 2021 13:27:56 +0200 [thread overview]
Message-ID: <20211008112717.253387748@linuxfoundation.org> (raw)
In-Reply-To: <20211008112716.914501436@linuxfoundation.org>
From: Linus Torvalds <torvalds@linux-foundation.org>
[ Upstream commit d8b1e10a2b8efaf71d151aa756052fbf2f3b6d57 ]
Guenter reported [1] that the pci_iounmap() changes remain problematic,
with sparc64 allnoconfig and tinyconfig still not building due to the
header file changes and confusion with the arch-specific pci_iounmap()
implementation.
I'm pretty convinced that sparc should just use GENERIC_IOMAP instead of
doing its own thing, since it turns out that the sparc64 version of
pci_iounmap() is somewhat buggy (see [2]). But in the meantime, this
just fixes the build by avoiding the trivial re-definition of the empty
case.
