[PATCH 2/6] drm/panel: Use devm_mipi_dsi_attach in Samsung panels

Osama Abdelkader <[email protected]>
Newsgroups org.freedesktop.lists.dri-devel,org.kernel.vger.linux-kernel
Message-ID <[email protected]> 
Use the managed MIPI DSI attach helper in Samsung panel drivers and drop the corresponding manual detach calls from remove paths.
