[PATCH] drm/i915: dump the device info

Daniel Vetter
2012-08-08T20:01:34Z

Handy for lazy people like me, or when people forget to add the output
of lspci -nn.

v2: Chris Wilson noticed that we have this duplicated already in the
i915_capabilites debugfs file. But there \n as separator looks better,
which would be a bit verbose in dmesg. Abuse the preprocessor to
extract this all.
