From eb0192fed016db1c5a9701cd6ca47233ff4a43e5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 30 Sep 2019 21:30:45 +0300 Subject: [PATCH] drm/i915: Fix g4x sprite scaling stride check with GTT remapping MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit I forgot to update the g4x sprite scaling stride check when GTT remapping was introduced. The stride of the original framebuffer is irrelevant when remapping is used and instead we want to check the stride of the remapped view. Also drop the duplicate width_bytes check. We already check that a few lines earlier.
