Subject: [PATCH 5.4 049/129] media: vicodec: add missing v4l2_ctrl_request_hdl_put()

From: Hans Verkuil <hverkuil-cisco@...all.nl>

[ Upstream commit 2e7c8fb8942773f412fe12f3b63e8bb92c18ab3f ]

The check for a required control in the request was missing a call to
v4l2_ctrl_request_hdl_put(), so the control request object was never
released.
