Stephane Grosjean 788199b73b can: peak_usb: fix USB FD devices potential malfunction
The latest firmware versions of USB CAN FD interfaces export the EP numbers
to be used to dialog with the device via the "type" field of a response to
a vendor request structure, particularly when its value is greater than or
equal to 2.

Correct the driver's test of this field.

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 reStructuredText 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.
