The code: trb->length = cpu_to_le32(TRB_BURST_LEN(priv_ep->trb_burst_size) | TRB_LEN(length)); TRB_BURST_LEN(priv_ep->trb_burst_size) may be overflow for int 32 if priv_ep->trb_burst_size is equal or larger than 0x80; Below is the Coverity warning: sign_extension: Suspicious implicit sign extension: priv_ep->trb_burst_size with type u8 (8 bits, unsigned) is promoted in priv_ep->trb_burst_size << 24 to type int (32 bits, signed), then sign-extended to type unsigned long (64 bits, unsigned). If priv_ep->trb_burst_size << 24 is greater than 0x7FFFFFFF, the upper bits of the result will all be 1. To fix it, it needs to add an explicit cast to unsigned int type for ((p) << 24).

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.
