The "rv" is initialized to "-ENOMEM", because "rv" is re-assigned to "-EINVAL", when kmalloc & usb_alloc_urb failed, the return value should return "-ENOMEM" rather than "-EINVAL",so the "rv" assignment is placed in the position where usb_endpoint_is_int_in is false.

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.
