[PATCH v10 09/16] cobalt: add .is_unordered() for cobalt

From: Ezequiel Garcia
Date: Mon May 21 2018 - 12:07:27 EST


From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxx>

The cobalt driver may reorder the capture buffers so we need to report
it as such.

v3: set formats as unordered
v2: use vb2_ops_set_unordered() helper
