The i2c subsystem currently blocks during adapter deregistration
whenever there are consumers holding a reference.
        
Switch to using of_get_i2c_adapter_by_node() which also takes a
reference to the adapter module so that an attempt to unload the module
while in use fails gracefully instead of blocking uninterruptibly.

Changes in v2:
 - fix a pre-existing leak in a corner case flagged by Sashiko that
   Doug thought was worth fixing
 - rebase module reference patch on top of that fix


Johan Hovold (2):
  drm/panel-edp: fix i2c adapter leak on probe failure
  drm/panel-edp: take i2c adapter module reference
