On code inspection, there are many instances in the driver where CEQE and AEQE fields written to by HW are read without guaranteeing that the polarity bit has been read and checked first. Add a read barrier to avoid reordering of loads on the CEQE/AEQE fields prior to checking the polarity bit.

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.
