Subject: drm/xe: Use __iomem for the regs pointer
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3ec276d06698189506f508f87c0f4f17c11e0251;p=linux.git

drm/xe: Use __iomem for the regs pointer

The regs pointer points to IO memory. Annotate it properly and
fix the corresponding sparse warning.
