From bbe2b06b55bc061c8fcec034ed26e88287f39143 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Thomas=20Hellstr=C3=B6m?= Date: Tue, 4 Mar 2025 18:33:40 +0100 Subject: [PATCH] drm/xe/hmm: Style- and include fixes MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add proper #ifndef around the xe_hmm.h header, proper spacing and since the documentation mostly follows kerneldoc format, make it kerneldoc. Also prepare for upcoming -stable fixes.
