This patch series aims to fix 2 bugs in the ADV7535 driver

1) use-after-free bug in adv7533_attach_dsi()
2) Drop unsupported single lane.

Changes in v7:

   with a NULL pointer. 
 - Added Rb tag from Laurent for patch#1.

 - Fixed memory leak by adding goto stattement in error path of
   adv7511_init_regulators().

Changes in v5:
 - Updated commit description for patch#1.
 - restored host_node in struct adv7511.
 - Dropped of_node_put() in adv7533_parse_dt() and calling of_node_put()
   in error path of probe() and also in the remove().
Changes in v4:
 - Updated commit description for patch#1.

   in probe(). Also freeing of host_node pointer after use is done in
   probe().

 - Replace __free construct with readable of_node_put().
 - Dropped single lane support from bindings and driver.
