media: hi556: Improve error logging when fwnode is not found

Browse source

The hi556 driver waits for the endpoint fwnode to show up in case this
fwnode is created by a bridge-driver.

It does this by returning -EPROBE_DEFER, but it does not use
dev_err_probe() so no reason for deferring gets registered.

After 30 seconds the kernel logs a warning that the probe is still
deferred, which looks like this:

[   33.952052] i2c i2c-INT3537:00: deferred probe pending: (reason unknown)

Use dev_err_probe() when returning -EPROBE_DEFER to register the probe
deferral reason changing the error to:

deferred probe pending: waiting for fwnode graph endpoint
