av_hwframe_transfer_data try with src_ctx first. If the operation
failed with AVERROR(ENOSYS), it will try again with dst_ctx. Return
AVERROR(EINVAL) makes the second step being skipped.

This one seems wrong? The user requested that (say) a YUV surface is
directly mapped to an RGB frame. That's an invalid request from the
user, not an unsupported feature.
If you're changing the return values then this test and the previous
one probably want to therefore be in the opposite order as well.
I was thinking about map between hardware pixel format. It's impossible
for the code path.
Patch v2 removed the change. Thanks for the review.
