commitd97c78a190upstream. According the programming guide (for all DWC3 IPs), when the driver handles ClearFeature(halt) request, it should issue CLEAR_STALL command _after_ the END_TRANSFER command completes. The END_TRANSFER command may take some time to complete. So, delay the ClearFeature(halt) request control status stage and wait for END_TRANSFER command completion interrupt. Only after END_TRANSFER command completes that the driver may issue CLEAR_STALL command.

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.
