Subject: [PATCH 5/7] media: hantro: Add helpers to prepare/finish a run
From: Boris Brezillon <boris.brezillon@...labora.com>
And use them where appropriate.
We might want to move hantro_{prepare,finish}_run() calls to
device_run() and have a 2-step approach similar to cedrus (prepare +
trigger) at some point, but let's keep that for later.
