From 932a9317ac492d4b93227357db4e3e2af28f0fbb Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Thu, 25 Jul 2019 10:17:54 -0400 Subject: [PATCH] media: hantro: Add helpers to prepare/finish a run 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.
