From: Tomi Valkeinen <tomi.valkeinen@xxxxxx>
Reading any of the DSI debugfs files results in a crash, as wrong
pointer is passed to the dump functions, and the dump functions use a
wrong pointer. This patch fixes DSI debug dumps.
Fixes: f3ed97f9ae7d ("drm/omap: dsi: Simplify debugfs implementation")
