From: Hans Verkuil Date: Fri, 13 Mar 2015 13:41:39 +0000 (-0300) Subject: [media] au0828: fix broken streaming X-Git-Tag: v4.1-rc1~59^2~1^2~201 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8a55ddd94c3a763f701f003fd56e39f7c317063d;p=karo-tx-linux.git [media] au0828: fix broken streaming Commit c5036d61e0bed3f4f51391a145638b426825e69c ("media: au0828: drop vbi_buffer_filled() and re-use buffer_filled()") broke video and vbi streaming. The vb2_buffer struct was copied instead of taking a pointer to it, but vb2_buffer_done() needs the real object, not a copy, since it is hooking the buffer into a different list.
