From 952c9ee2900de152c4999d94da5c4bd846ae52e8 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 10 Feb 2014 13:12:00 -0300 Subject: [PATCH] [media] vb2: fix PREPARE_BUF regression Fix an incorrect test in vb2_internal_qbuf() where only DEQUEUED buffers are allowed. But PREPARED buffers are also OK. Introduced by commit 4138111a27859dcc56a5592c804dd16bb12a23d1 ("vb2: simplify qbuf/prepare_buf by removing callback").
