Subject: isl: Add struct isl_device
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b1bb270590ae969b86a3f838d83e06466f345723;p=mesa.git

isl: Add struct isl_device

The struct is incomplete (it contains only the gen). And it's nowhere
used yet.

It will be used later for surface layout calculations.
