Subject: media: mei: csi: Warn less verbosely of a missing device fwnode
Author: Sakari Ailus <sakari.ai...@linux.intel.com>
Date: Mon May 27 23:13:27 2024 +0300
The check for having device fwnode was meant to be a sanity check but this
also happens if the ACPI DSDT has graph port nodes on sensor device(s) but
not on the IVSC device. Use a more meaningful warning message to tell
about this.
Fixes: 33116eb12c6b ("media: ivsc: csi: Use IPU bridge")
