A USB peripheral can respond with a NAK if it is not yet ready to send/receive data. In this case, the transaction should be retried. The MAX3421 driver did do this, and switched to a different type of retry after a number of 'fast' retries. On at least some USB flash devices, this second type of retry never succeeds. This patch changes the behaviour so that 'fast' retries continue.

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.
