From 509e42ce0441df39d5241150c1bec32cf6347b6c Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Fri, 12 Feb 2016 14:48:33 +0530 Subject: [PATCH] drm/dsi: Add routine to unregister a DSI device A driver calling mipi_dsi_device_register_full() might want to remove the device once it's done. It might also require it in an error handling path in case something went wrong. Create mipi_dsi_device_unregister() for this purpose and use it within mipi_dsi_remove_device_fn() as it does the same thing.
