[ Upstream commit 4f6c11044f512356cb63d3df0f3b38db79dc6736 ]
Two orthogonal changesets caused a breakage at a printk inside davinci. Commit a2d17962c9ca ("[media] davinci: Switch from V4L2 OF to V4L2 fwnode") made davinci to use struct fwnode_handle instead of struct device_node. Commit 68d9c47b1679 ("media: Convert to using %pOF instead of full_name") changed the printk to not use ->full_name, but, instead, to rely on %pOF.
With both patches applied, the Kernel will do the wrong thing, as warned by smatch: drivers/media/platform/davinci/vpif_capture.c:1399 vpif_async_bound() error: '%pOF' expects argument of type 'struct device_node*', argument 5 has type 'void*'
So, change the logic to actually print the device name that was obtained before the print logic.
Fixes: 68d9c47b1679 ("media: Convert to using %pOF instead of full_name") Fixes: a2d17962c9ca ("[media] davinci: Switch from V4L2 OF to V4L2 fwnode")
