Subject: media: atomisp: Prefix firmware paths with "intel/ipu/"
Author:  Hans de Goede <hdego...@redhat.com>
Date:    Mon Jun 3 15:20:55 2024 +0200

The atomisp firmwares have been added to upstream linux-firmware
under intel/ipu/ add this prefix to the firmware name passed
to request_firmware().

Fall back to the old location if this fails to avoid breaking existing
setups.
