[PATCH 5.4 050/129] media: cedrus: Add missing v4l2_ctrl_request_hdl_put()

[Greg Kroah-Hartman]

From: Ezequiel Garcia <ezequiel@xxxxxxxxxxxxx>

[ Upstream commit b30063976f29fc221a99d18d37d22ca035068aa9 ]

The check for a required control in the request was missing a call to
v4l2_ctrl_request_hdl_put() in the error path. Fix it.

Fixes: 50e761516f2b8c ("media: platform: Add Cedrus VPU decoder driver")
