commit242439f7e2upstream. The expression for setting the size of the allocated bulk TX buffer (`devpriv->usb_tx_buf`) is calling `usb_endpoint_maxp(devpriv->ep_rx)`, which is using the wrong endpoint (should be `devpriv->ep_tx`). Fix it.

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.
