'usb_free_urb(urb)' is a no-op, because urb is known to be NULL.
It is likelly that releasing resources allocated by
'tm6000_alloc_urb_buffers()' just a few lines above is expected here.
This has been spotted by the following coccinelle script:
@@
expression ret, x, e;
identifier f;
@@
* if (x == NULL)
{
... when != x = e;
(
* f(<+...x...+>);
|
* ret = f(<+...x...+>);
)
...
}

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
