From: "Dr. David Alan Gilbert" <linux@xxxxxxxxxxx>
ipu_image_convert_enum_format() and ipu_image_convert_sync() were both
added in 2016 by
commit cd98e85a6b78 ("gpu: ipu-v3: Add queued image conversion support")
but have remained unused.
Remove them.
ipu_image_convert_sync() was the last user of
image_convert_sync_complete().
Remove it.
