Subject: i965/miptree: Remove the stencil_as_y_tiled parameter from get_aligned_offset
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c30b7164b757e5ee68f4856adecc6b720ff9d941;p=mesa.git

i965/miptree: Remove the stencil_as_y_tiled parameter from get_aligned_offset

The only actual user of this parameter was blorp and, since the conversion
to ISL, it no longer uses this function.
