Subject: [PATCH] fixup! staging: vc04_services: bcm2835-isp: Add a more complex ISP processing component

Setup DMA Mask

I realised while (re)creating the test branches (sent in reply to the cover
letter), I missed to squash this hunk in
"staging: vc04_services: bcm2835-isp: Add a more complex ISP processing component"
before sending out the series.

Sending it as a fixup! for now.
