Subject: [DO NOT REVIEW 05/11] drm/xe/display: Remove duplicated code
Date: Mon, 20 Jul 2026 18:14:57 +0200	[thread overview]
Message-ID: <20260720161451.384968-18-dev@lankhorst.se> (raw)
In-Reply-To: <20260720161451.384968-13-dev@lankhorst.se>

The order of pte vs checks isn't important, so read the pte
outside the if block. This makes it slightly more readable.
