[v3] media: v4l2-fwnode: Simplify v4l2_async_nf_parse_fwnode_endpoints()
Commit Message
There are only one user left of __v4l2_async_notifier_parse_fwnode_ep()
since [1], v4l2_async_notifier_parse_fwnode_endpoints(). The two
functions can be merged.
The merge of the two highlights a dead code block conditioned by the
argument 'has_port' that always is false and can therefor be removed.
1. commit 0ae426ebd0dcef81 ("media: v4l2-fwnode: Remove v4l2_async_notifier_parse_fwnode_endpoints_by_port()")
Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>
---
* Changes since v2
- Extend commit message to describe that the dead code removed is created
by the merge of the two functions.
- The rename of the effected function never made it upstream, rebase
this patch to latest media-tree so it can be picked-up without the
rename.
* Changes since v1
- Rebased on Sakari's branch which renames
v4l2_async_notifier_parse_fwnode_endpoints() to
v4l2_async_nf_parse_fwnode_endpoints).

I've continued work on the rename, and I'm about to send a new version.
So I'll take the commit message changes from this one if that's fine for
you.
