Subject: i965/miptree: Store chars-per-pixel even for isl based
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8e1494f13993c5c1e260be4cd92398714de28e32;p=mesa.git

i965/miptree: Store chars-per-pixel even for isl based

This will significantly reduce chrun when switching remaaining
surface types to isl. After the full transition it will be easier
to calculate on-demand and drop the helper member in miptree.
