Commit Message

Dr. David Alan Gilbert Dec. 26, 2024, 2:27 a.m. UTC 
From: "Dr. David Alan Gilbert" <linux@treblig.org>

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.
