[ Upstream commit 8d4e29a51a954b43e06d916772fa4f50b7e5bbd6 ]
In the patch refactoring the fw-node, the mt9m111 was broken for all platform_data based platforms, which were the first aim of this driver. Only the devicetree platform are still functional, probably because the testing was done on these.
The result is that -EINVAL is systematically return for such platforms, what this patch fixes.
[Sakari Ailus: Rework this to resolve a merge conflict and use dev_fwnode]
