Also, currently, there is no way to protect the DPI driver data. All DPI panel drivers don't ensure this, and in general, a DPI panel driver should use it's lock to that ensure it's own driver data and omap_dss_device states are taken care of, and not worry about the DPI interface. Add mutex locking in the DPI enable/disable/set_timings ops. Signed-off-by: Archit Taneja --- Reading git-diff-tree failed
