drm: bridge: it66121: Check drm_bridge_attach retval 
The return value of drm_bridge_attach() is ignored during
the it66121_bridge_attach() call, which is incorrect.

337ed732b3 drm: bridge: it66121: fix a resource leak in probe 
In the original code if the "ctx = devm_kzalloc()" allocation failed
then we should have called of_node_put(ep); before returning.  It's
actually a bit easier to do the allocation first before assigning
ep = of_graph_get_endpoint_by_regs().

69fbffcc30 drm: bridge: it66121: fix an error code in it66121_probe() 
This code is passing the wrong variable to PTR_ERR() so it doesn't
return the correct error code.
