[ Upstream commit 5d3c8990e2bbf929cb211563dadd70708f42e4e6 ]
The dma_q->p_left_data alloced by kzalloc should be freed in all the
following error handling paths. However, it hasn't been freed in the
allocation error paths of dev->video_mode.isoc_ctl.urb and
dev->video_mode.isoc_ctl.transfer_buffer.
On the other hand, the dma_q->p_left_data did be freed in the
error-handling paths after that of dev->video_mode.isoc_ctl.urb and
dev->video_mode.isoc_ctl.transfer_buffer, by calling
cx231xx_uninit_isoc(dev). So the same free operation should be done in
error-handling paths of those two allocation.
Fixes: 64fbf4445526 ("[media] cx231xx: Added support for Carraera, Shelby, RDx_253S and VIDEO_GRABBER")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
