Subject: r600: fix copy/paste bug for sampleMaskIn workaround
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=53959fcbd88f38316359aa7b48cb9464c23eb870;p=mesa.git

r600: fix copy/paste bug for sampleMaskIn workaround

The sampleMaskIn workaround (b936f4d1ca0d2ab1e828ff6a6e617f12469687fa)
tries to figure out if the shader is running at per-sample frequency, but
there's a typo bug so it will only recognize per-sample linar inputs,
not per-sample perspective ones.

Spotted by Eric Engestrom <eric.engestrom@intel.com>

Fixes: b936f4d1ca0d2ab1e828a "r600: partly fix sampleMaskIn value"
