sparse problem with duplicate __iomem?

[Randy Dunlap <rdunlap@xxxxxxxxxxxxx>]

Hi,

On kernel 5.9-rc1, either i386 or x86_64 builds, I am seeing these
sparse warnings:

../drivers/gpu/drm/ast/ast_cursor.c:256:26: CK: warning: duplicate [noderef]
../drivers/gpu/drm/ast/ast_cursor.c:256:26: CK: error: multiple address space given: __iomem & __iomem

for this source line:

	u8 __iomem *dst, __iomem *sig;


Should one of those __iomem-s be removed?
I.e., does "__iomem" apply to everything after it, up to the ending ';',
or just up to the next comma ','? 


thanks.
