Subject: [PATCH v3] media: v4l2-fwnode: Simplify v4l2_async_nf_parse_fwnode_endpoints()
Date: Sun, 13 Jun 2021 17:08:47 +0200	[thread overview]
Message-ID: <20210613150847.774978-1-niklas.soderlund+renesas@ragnatech.se> (raw)

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).
