Subject: [PATCH 03/22] media: entity: Convert media_entity_get_fwnode_pad() args to const
Date: Mon,  5 Aug 2019 16:34:46 -0700	[thread overview]
Message-ID: <20190805233505.21167-4-slongerbeam@gmail.com> (raw)
In-Reply-To: <20190805233505.21167-1-slongerbeam@gmail.com>

The function media_entity_get_fwnode_pad() can be passed the
const local_fwnode member from a struct fwnode_endpoint, so
the fwnode argument should be a const pointer. Change the
direction_flags argument to const in the process.
