Subject: [PATCH v3 4/6] drm/panel: Use devm_mipi_dsi_attach in Himax and Ilitek panels
Date: Wed, 12 Aug 2026 15:04:21 +0200	[thread overview]
Message-ID: <20260812130429.16850-4-osama.abdelkader@gmail.com> (raw)
In-Reply-To: <20260812130429.16850-1-osama.abdelkader@gmail.com>

Use the managed MIPI DSI attach helper in Himax and Ilitek panel drivers
and drop the corresponding manual detach calls from remove paths.

Signed-off-by: Osama Abdelkader <osama.abdelkader@gmail.com>
