Subject: [PATCH 5/6] sparc: move the leon PCI memory space comment to <asm/leon.h>
Date: Sat,  8 Dec 2018 09:41:14 -0800	[thread overview]
Message-ID: <20181208174115.16237-6-hch@lst.de> (raw)
In-Reply-To: <20181208174115.16237-1-hch@lst.de>

It has nothing to do with the content of the pci.h header.

Suggested by: Sam Ravnborg <sam@ravnborg.org>
Signed-off-by: Christoph Hellwig <hch@lst.de>
