Introduce managed versions of both functions.
They allows to simplify the error path in the probe function of
rc drivers, and usually also to simplify the remove function.

New element managed_alloc in struct rc_dev is needed to correctly
handle mixed use, e.g. managed version of rc_register_device and
normal version of rc_allocate_device.

In addition devm_rc_allocate_device sets rc->dev.parent as having a
reference to the parent device might be useful for future extensions.

9b26336356 [media] lirc_imon: use complete() instead complete_all()
There is only one waiter for the completion, therefore there
is no need to use complete_all(). Let's make that clear by
using complete() instead of complete_all().

While we are at it, we do a small optimization with the
reinitialization of the completion before we use it.

The usage pattern of the completion is:

waiter context                          waker context

send_packet()
  reinit_completion()
  usb_sumbit_urb()
  wait_for_completion_interruptible()

                                        usb_tx_callback()
                                          complete()

                                        imon_disconnect()
                                          complete()

c57a68a152 [media] media: adv7604: automatic "default-input" selection
Documentation states that the "default-input" property should reside
directly in the node of the device.  This adjusts the parsing to make the
implementation consistent with the documentation.

Based on patch by William Towle <william.towle@codethink.co.uk>.
