Subject: [PATCH v2 10/23] media: st-mipid02: Fix fwnode media link creation
Date: Sun, 24 Nov 2019 11:06:50 -0800 [thread overview]
Message-ID: <20191124190703.12138-11-slongerbeam@gmail.com> (raw)
In-Reply-To: <20191124190703.12138-1-slongerbeam@gmail.com>
mipid02_async_bound() passes the bound subdev's sd->fwnode to
media_entity_get_fwnode_pad(). This is likely not an endpoint
fwnode as required by media_entity_get_fwnode_pad(), for most
subdevices it is the port parent of endpoint fwnode(s). This has only
worked before because no entities have implemented the .get_fwnode_pad()
op yet, and the default behavior of media_entity_get_fwnode_pad()
was to ignore the passed fwnode and return the first pad that matches
the given direction flags.
Fix this by replacing the calls to media_entity_get_fwnode_pad() and
media_create_pad_link() with a call to media_create_fwnode_pad_links().
Fixes: 642bb5e88fed8 ("media: st-mipid02: MIPID02 CSI-2 to PARALLEL
bridge driver")
