Subject: [PATCH v3 07/17] drm/panthor: Move the debugfs initialization to panthor_device.c
Date: Thu, 13 Aug 2026 12:57:05 +0200	[thread overview]
Message-ID: <20260813-panthor-unplug-fixes-v3-7-3ed4e961bbe7@collabora.com> (raw)
In-Reply-To: <20260813-panthor-unplug-fixes-v3-0-3ed4e961bbe7@collabora.com>

Those are per-device debugfs-files, so it makes sense to have the
initialization logic in panthor_device.c.
