Currently, there are not checks if something gets bad during memory allocation: it will simply use NULL pointers and crash. Add error path at the logic which allocates memory for the MPEG-TS generator code, propagating the errors up to the vidtv_bridge. Now, if something wents bad, start_streaming will return an error that userspace can detect: ERROR DMX_SET_PES_FILTER failed (PID = 0x2000): 12 Cannot allocate memory and the driver doesn't crash.

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.
