Description
In the Linux kernel, the following vulnerability has been resolved: fbdev: omapfb: panel-dsi-cm: initialize lock before registering display dsicm_probe() registers the display before initializing ddata->lock. Once omapdss_register_display() publishes the display, another consumer can reach a dsicm callback that takes this mutex while it is still uninitialized. Initialize the mutex before registering the display so the published callbacks always see a valid lock.
